Description of the assessment of CONSORT criteria recommended in the extension to CONSORT for non-inferiority and equivalence trials [11] (R = reporting item, M = methodological item, I = interpretation)

CONSORT criteria Included in present evaluation Category Description of assessed variables
Specify that the trial is a non-inferiority or equivalence trial
Yes
R
Clearly identified as non-inferiority or equivalence trial in title, abstract or full paper
Rationale for using a non-inferiority or equivalence design
Yes
R
Justification stated for using a non-inferiority or equivalence design
Eligibility for participants with respect to trials that established efficacy of the reference treatment
No
-
-
Interventions intended for each group with respect to trials that established efficacy of the reference treatment
No
-
-
Specific objectives and hypothesis concerning non-inferiority or equivalence
Yes
R
Hypothesis stated clearly (text or formula)
M
Margin defined
Clearly defined primary and secondary outcome measures with respect to trials that established efficacy of the reference treatment
(Yes)
R
Primary outcome identified clearly (not evaluated whether outcome is identical to those in any trial that established efficacy of the reference treatment)
Sample size calculation using a non-inferiority or equivalence criterion and specifying the margin with the rationale for its choice. When applicable, explanation of any interim analyses and stopping rules (and whether related to a non-inferiority or equivalence hypothesis)
Yes
R
Sample size calculation presented
R
Elements for recalculation of sample size reported
M
Margin considered
R
Justification for margin stated
R
Interim analyses planned
Method used to generate random allocation sequence including details of any restriction
Yes
R
Method of randomisation reported
R
Restriction method reported (blocking/stratification/minimisation)
Method used to implement allocation concealment
No
-
-
Who generated the allocation sequence and enrolled and assigned participants
No
-
-
Whether participants, those administering the interventions and those assessing the outcome were blinded to group allocation
Yes
R
Method of blinding reported (any blinding; single blind, double blind, open or double dummy design)
Statistical methods used to compare groups for primary outcome specifying whether a 1- or 2-sided confidence interval approach was used. Methods for additional analyses (subgroups, adjusted analyses)
Yes
R
Statistical methods used for comparison reported
Participant flow through each state of the trial (diagram strongly recommended)
Yes
R
Diagram of flow of participants presented
Dates defining the periods of recruitment and follow-up
Yes
R
Dates reported
Baseline information for each group
Yes
R
Baseline information presented for each group

Yes
R
Number of participants reported - similar to 13
R
Analysis sets reported
M
Results of ITT and per-protocol analysis presented
For each outcome, a summary of results for each group and the estimated effect size and its precision (useful: figure showing confidence intervals and margins)
Yes
M
Results presented using a confidence interval
R
Report of confidence level and 1- or 2-sided
R
Report of P-value
R
Figure presented
Address multiplicity by reporting any other analyses performed
No

-
All important adverse events or side effects in each group
Yes
R
Adverse events reported
Interpretation of the results taking into account the non-inferiority or equivalence hypothesis, sources of potential bias or imprecision
Yes
I
Interpretation of results presented
Interpretation correct (non-inferiority/equivalence/superiority/inferiority/inconclusive result/wrong/incomprehensible by means of presented results)
Statement on expected advantage
Generalisability (external validity) of the trial findings
No
-
-
General interpretation of the results in the context of current evidence No - -
