Three-Arm CONSORT Flow Diagram

Three-arm CONSORT flow diagram

A three-arm CONSORT flow diagram extends the usual parallel trial structure by adding one allocation branch. The enrollment section records who was assessed, excluded, and randomized. Each arm then needs its own allocation, follow-up, and analysis counts. Put the treatment or dose name in the allocation box so readers can match the branch to the study methods. If participants discontinue or are excluded from analysis, record the count and reason in the correct branch. Keeping each arm aligned beneath randomization makes it easy to compare retention and analysis populations across all groups. Use the final counts that correspond to the analysis described in the results.

01Common entry

Keep screening and randomization together before branches.

02Equal allocation

Label the assigned count for every arm.

03Parallel follow-up

Show completion separately in each arm.

04Final analysis

Keep analysed counts directly below their arm.

Use this for trials comparing two active doses with placebo or any other three parallel treatment groups.

الأسئلة الشائعة

أسئلة شائعة

Can a CONSORT diagram show three study arms?

Yes. Add a parallel branch for each allocation arm and continue each through follow-up and analysis.

Where do dose names go?

Put them in the allocation labels so each branch clearly identifies its intervention.

How should follow-up be reported?

Give the completed, lost, or discontinued counts separately for every arm.
