“Draw a two-arm CONSORT flow diagram with 240 assessed, 40 excluded, 200 randomized, 100 allocated to intervention and 100 to control, received counts, follow-up losses and discontinuations, and 95 versus 97 analysed.”
図の背後にある意思決定を読み解く。
Show everyone assessed before exclusions.
Keep randomized participants separate by study arm.
State losses and discontinuations before analysis.
Report the count included in each final analysis.
Use this structure for a standard two-arm randomized controlled trial with a single follow-up period.
よくある質問
What counts belong in a CONSORT flow diagram?
Show counts for assessment, exclusion, randomization, allocation, follow-up, and analysis, with reasons where participants leave the study.
Should each study arm have its own branch?
Yes. Separate branches make allocation, attrition, and final analysis counts clear for each arm.
Do the counts need to reconcile?
Yes. The participant totals at each stage should explain how the randomized total leads to the final analysis sets.
