20. Introduction: Background and rationale
6a.Description of research question and justification,
summary of relevant studies examining benefits and
harms
• Summarize the importance of the research question
• Justify the need for the trial in the context of available evidences
• Strongly recommended that an up-to-date systematic review of
relevant studies be summarized and cited in the protocol
• Failure to do so leads to unnecessary research and exposes participants
to possible harms
21. Background and rationale choice of comparators
6b.Explanation for choice of comparators
• Clear description of the rationale for the comparator intervention
• Standard treatment in that condition
• Ex: inappropriately low dose of active drug in control will overestimate
the relative efficacy of study intervention in real practice
22. Objectives
7. Specific objectives or hypotheses
• Reflect the scientific question to be answered
• Generally phrased using neutral wording rather than particular direction
of effect
• For multi-arm trials, clarify the way the way in which all the treatment
groups will be compared (eg, A vs B; A vs C), in what outcome
23. Trial design
8. Description of trial design including type of trial,
allocation ratio, and framework
• Types: parallel group, crossover, factorial, single group
• Framework: superiority, equivalence, non-inferiority, exploratory
• Most common design: parallel group, two-arm, superiority trial with 1:1
allocation ratio.
24. Methods participant
9. Description of study settings and list of countries where
data will be collected
• At minimum:
• Countries
• Types of setting (urban/rural/hospital/community-based)
• Likely number of study sites
25. Eligibility criteria
10.Inclusion and exclusion criteria for participants,
eligibility criteria for study centers and individuals who
perform intervention (surgeon)
• Define the study population
• Eligibility for care provider
• Promote consistency of intervention
• Clear description of eligibility criteria
• Enables study personnel to apply these criteria consistently throughout the trial
• Convey key information related to external validity (generalizability)
26.
27. Interventions
11a. Interventions for each group with sufficient detail to
allow replication (including how and when)
• Drugs/biological agents/placebos • Non-drug
• Generic name • Details about setting (Item 9)
• Manufacturer • Details of individuals administering
• Constituent components intervention (pre-trial expertise,
• Route of administration specific training)
• Dosing schedule (including titration
and run-in periods if applicable)
28.
29. Interventions modifications
11b. Criteria for discontinuing or modifying allocated
interventions for given trial participants
• Define standard criteria for intervention modifications and
discontinuations
• Study participants should be retained in the trial whenever possible to
enable follow-up data collection and prevent missing data
30.
31. Interventions adherence
11c. Strategies to improve adherence to intervention
protocols and procedures to monitor adherence
• Low adherence: effect on statistical power and interpretation of trial
result
• Description of procedures and strategies for monitoring and improving
adherence
32. Interventions concomitant care
11d. Concomitant care & interventions permitted or
prohibited during the trial
• Co-intervention bias: when study groups receive different
care/intervention (in addition to assigned trial intervention) that may
affect outcomes
• Protocol should list concomitant care and interventions that are
allowed, including rescue intervention
33. Outcomes
12. Primary, secondary, other outcomes
• Protocols should define four components for each outcome
1. Specific measurement variables (e.g. systolic BP)
2. Specific measurement time point of interest for analysis
3. Analysis metric (e.g. change from baseline, final value, actual value changes
over time, time to event)
4. Method of aggregation (mean ( median), proportion , rate)
• Explain the rationale
• Number of primary outcomes should be as small as possible
• Problems of multiplicity, selective reporting, and interpretation when there are
inconsistent results among outcomes
34. 12. Primary, secondary, other outcomes (continued)
• Development of common set of key outcomes within a specialty can
help to deter selective reporting & facilitate comparisons and pooling in
meta-analysis
• COMET (Core Outcome Measures in Effectiveness Trials) initiatives
facilitate development and application of such standardized sets
• www.comet-initiative.org
35.
36. Participant timeline
13. Time schedule of enrolment, interventions, assessments,
and visits for participants. Schematic diagram highly
recommended
• Clear and concise timeline helps guide trial conduct and enables
external review of burden and feasibility
• Key information
• Timing of each visit
• Time periods during which trial interventions will be administered
• Procedures and assessments performed at each visit
37.
38. Sample size
14. Estimated number of participants needed to achieve
study objectives and how it was determined
• If sample size is not derived statistically, then this should be explicitly
stated along with rationale (exploratory pilot studies; pragmatic
consideration for rare diseases)
• Calculation based on one primary outcome
• Also worthwhile calculating power that will be available for other outcomes
39. Report
• Outcomes
• Value assumed for outcome in each group particularly in comparators
with citation
• Statistical test
• Alpha (Type I error) level
• Power
• Calculated sample size per group
40.
41. Recruitment
15. Strategies for achieving adequate participant
enrolment to reach target sample size
• Description of where participants will be recruited (clinic, community),
by who, and how (advertisement, review of health records)
• Expected recruitment rates
• Duration of recruitment periods
• Plans to monitor recruitment
• Financial/nonfinancial incentives provided to trial
investigators/participants
42. Allocation-sequence generation
16a. Method of generating the allocation sequence and list
of any factors for stratification.
• Randomization:
• Decrease selection bias in allocation
• Help blinding
• Enable the use of probability theory to test the difference in outcome between
groups
• Use of "randomization" term without further elaboration is not
sufficient
• If non-random allocation is planned, specific method and rationale
should be stated.
43. Key elements of random sequence to
specify
• Method of sequence generation (random number table/generator)
• Allocation ratio
• Type of randomization and reason
• Factors used for stratification
45. Simple randomization
• Based on single, constant allocation ratio
• 1:1 allocation – analogous to coin toss
• No other allocation approach surpasses
the bias prevention and unpredictability of
simple randomization
46. Restricted randomization
• Any randomization approach that is not simple randomization
• Blocked randomization (permuted block randomization)
• Assures that study groups of approximately the same size will be generated
when an allocation of 1:1 is used
• Ensures close balance of groups at any time during the trial
• Reducing the unpredictability of the sequence
• Blinding, larger block size, randomly varying block size will reduce this problem
47. Restricted randomization
• Stratified randomization
• Ensured good balance of participant characteristics in each group
• Separate randomization within each of two or more strata of participants (e.g.,
categories of age)
• Requires some form of restriction (e.g., blocking within strata)
• Number of strata should be limited to avoid over-stratification
• Example: Stratified by center in multicenter trial
• Biased coin and urn randomization
• Attain similar objective as blocked design without forcing strict equality
• Alter the allocation ratio during the course of the trial to rectify imbalances that
might be occurring
• Urn randomization: varying allocation ratios based on the magnitude of the
imbalance
48. Biased Coin
• Altering allocation probability during the
course of the trial to rectify balances in
group numbers
• Example:
• start with 0.5 / 0.5 probability
• If the disparity reaches the limit the
probability change to : 0.6 / 0.4
49. Urn Randomization
• Adaptive biased-coin
• UD (α,β) – UD (2,1)
• Urn contained 2 (α) blue balls and 2 green balls
(0.5 / 0.5 probability)
• Drawn ball at random
• Replace ball with two balls (one blue, one green)
and one (β) additional ball of opposite color
• Change in probability during each assignment
50. Restricted randomization
• Minimization
• Assures similar distribution of selected participant factors between study groups
• Randomization lists are not set up in advance
• First participant is truly randomly allocated
• Subsequent participant: treatment allocation that minimizes the imbalance on
the selected factors between group at the time
• Advantage: making small groups closely similar in terms of participant
characteristics at all stages of trial
• Some methodologists considered superior to randomization
• For SPIRIT, minimization is considered a restricted randomization
51. Need for separate document to describe
restricted randomization
• If some type of restricted randomization is to be used (blocked /
minimization) the knowledge of specific details could lead to bias
• If block size is 6, trial implementers know that if two As and three Bs have
already been done, they will know the next one
• This is a problem in both open label and ineffectively blinded trials
• Do not provide the full details of a restricted randomization scheme
(including minimization) in the trial protocol
• Simple randomization procedures should be reported in detail because
simple randomization is totally unpredictable
52. Allocation concealment mechanism
16b. Mechanism of implementing the allocation sequence
(e.g., telephone; envelopes), describing any steps to
conceal the sequence
• Concealment aims to prevent participants and recruiters from knowing
the study group to which the next participant will be assigned
• Common practice: enclose assignments in sequentially numbered,
sealed, opaque envelopes
53.
54. Allocation implementation
16c. Who will generate sequence, who will enroll
participants, and who will assign participants to
intervention
• Complete separation of 2 groups of individuals
1. Involved in steps before enrolment (sequence generation, allocation
concealment)
2. Involved in implementation of study group assignments
• Specify
• Who will implement randomization process
• How and where allocation list will be stored
• Mechanisms to minimize possibility that those enrolling individuals have access
to list
55. Blinding (Masking)
17a. Who will be blinded after assignment to interventions
and how
• Awareness of intervention can introduce:
• Ascertainment bias (different outcome measurements)
• Performance bias (decision to discontinue/modify intervention)
• Concomitant intervention
• Exclusion/attrition bias (decision to withdraw/exclude from analysis)
• When blinding is not possible (obvious differences in interventions):
• Blind outcome assessors
• Blind hypothesis in terms of which intervention is considered active
56. • Description of who is blinded is preferred over ambiguous terminology
such as “double blind”
• Trial participants
• Care providers
• Data collectors
• Outcome assessors
• Data analysts
• Manuscript writers
• Describe the comparability of blinded intervention
• Appearance
• Flavor/taste
• Timing of final unblinding (e.g. after the creation of a locked analysis data set)
57. • Strategies to reduce potential for unblinding
• Pre-trial testing of blinding procedures
• Use unique code for each participants rather than fixed code (A=Group1,
B=Group2)
• Unblinding of one participant will result in the loss of blinding for all participants
58. Blinding (Masking) emergency unblinding
17b. Circumstances under which unblinding is permissible
intervention during the trial
• Emergency unblinding intended to increase the safety of trial
participants
• Clear description of emergency unblinding
• Prevent unnecessary unblinding
• Facilitates implementation
• Enables evaluation of appropriateness of planned procedures
59. Methods data collection, management, and analysis
18a. Plans for assessment and collection of outcome,
baseline, and other trial data
• Related process to promote data quality
• Duplicate measurement, training of assessors
• Description of study instruments
• Questionnaire, laboratory tests
• Reliability and validity of instruments
• Where data collection form can be found if not in the protocol
60. • Validity and reliability of trial data depends on quality of data collection
• Avoid
• Modified versions of validated measurement tools: no longer be considered
validated
• Unpublished measurement scales
• Standard process should be implemented by local study personnel to
enhance data quality and reduce bias
• Inclusion of data collection forms in the protocol (i.e., as appendices) is
highly recommended
61. Data collection method retention
18b. Plans to promote retention and complete follow-up,
list of any outcome data to be collected for those who
discontinue or deviate from protocols
• Non-retention: participants are prematurely “off study”
• Consent withdrawn
• Lost to follow-up
• Plan for how to promote retention in order to prevent missing data
• Methods:
• Financial reimbursement
• Systematic methods and reminders for contacting patients
• Scheduling appointments
• Monitoring retention
• Limiting burden related to follow-up visits and procedures
62. • Non-adherence: deviation from intervention protocol
• Does not mean “off study”
• Should not be reason for ceasing to collect data
• All participants be included in an intention-to-treat analysis, regardless
of adherence
• Describe
• Retention strategies
• What to record from non-adherence participants
• Plan to record reasons for non-adherence and non-retention
63. Data Management

including process to promote quality (double entry,
range checks)
• Full description of data entry and coding process
• Measures to promote data quality
• Document data security measures to prevent unauthorized access
• Plans for data storage during and after trial

observer variations
64. Data entry
• Local data entry
• Fast correction of missing/inaccurate data
• Central data entry (in paper forms)
• Facilitates blinding
• Standardization
• Training of a core group of data entry
personnel
65. Data entry
• Standard process to improve accuracy of data entry and coding
• Verification of proper format (integer)
• Expected range check
• Double data entry (but weigh time and costs against the magnitude of reduction
in error rates)
66. Statistical methods
• Should be fully described in the protocol

specified (e.g. method of examining
pattern of missing data) then outline
planned approach to making final
choice
• May have a separate document:
statistical analysis plan (SAP)

will be used, as well as intended use of confidence intervals
68. • Specify which comparisons (one or more study groups) will be
performed, and which will be the main comparison of interest
• Reduce risk of false positives (type I) when multiple statistical comparisons are
performed
• Different trial designs dictate most appropriate plans and additional
relevant information
• Cluster, factorial, crossover, within-person trial requires specific statistical
consideration
69. Statistical methods additional analyses
20b. Methods for any additional analyses (e.g., subgroup
and adjusted analysis)
• Subgroup analysis
• Often selectively reported or not specified
• Post hoc analyses: high risk of spurious findings and are discouraged
• Preplanned subgroup analysis should be clearly specified
• Definition of categories
• Statistical method
• Hypothesized direction of subgroup effect based on plausibility
70. • Adjusted analysis
• Indicate if there is intention to perform or consider adjusted analyses
• Explicitly specifying any variables for adjustment and how variables will be
handled
• If it is not clear which variable will be important for adjustment, objective
criteria to be used to select variables should be pre-specified
71. Statistical methods analysis population and missing data
20c. Definition of analysis population relating to protocol
non-adherence and statistical methods to handle
missing data
• Intention to treat (ITT) analysis
• “as randomized” analysis retains participants in the group which they were
originally allocated
• Included outcome data obtained from all participants regardless of protocol
adherence
• Modification of ITT can introduce bias
• Particularly if the frequency of and reasons for non-adherence vary between
groups
72.
73. • Explicitly describe which participants will be included in the main
analysis (e.g., all randomized participants, regardless of protocol
adherence)
• Avoid ambiguous use of labels such as “intention to treat” or “per
protocol” unless they are fully defined in protocol
• Most analyses labelled as such do not actually adhere to the definition
74. Missing Data Strategies
• Address how missing data will be handled and planned methods to
impute (estimate) missing data
• Methods of multiple imputation are more complex, but preferred to
single imputation (e.g., last observation carried forward)
• Sensitivity analyses are highly recommended to assess the robustness of
trial results under different methods of handling missing data
75. Data monitoring formal committee
21a. Composition of data monitoring committee (DMC),
roles and reporting structure; whether it is independent
from sponsor and competing interests
