In plain language

Across 5 trials with 866 participants, 0 of 8 treatments had a clearly better result than placebo on constipation, and for 8 the evidence could not tell them apart from placebo. The most favorable estimate was for Semaglutide 2.4 mg subcutaneous once weekly: hazard ratio (from event counts) 0.78 (95% credible interval 0.12 to 5.87).

Lower values favor the treatment. "Clearly" means the 95% credible interval excludes no difference. These are averages across trials; they do not say how any one person will respond. Not medical advice.

Network of trials

Each circle is a treatment; each line joins treatments that were randomized against each other in at least one trial.

Inconsistency

Do trials comparing two treatments directly agree with the indirect evidence through other treatments?

No comparison here has both direct and indirect evidence, so inconsistency cannot be checked by node splitting; the between designs Q above is the global check.

Small study effects

A comparison adjusted funnel plot: each point is one trial comparison, centered on its own network estimate. Asymmetry can signal that small trials with unfavorable results are missing.

Fewer than ten trial comparisons, too few to judge funnel plot asymmetry.

Comparability of the trials

Checked across designs (the set of treatments each trial compares) for eligibility, outcome definition and assessment, and the baseline factors above. Flags point to possible intransitivity; notes describe variation that is not tied to design.
  • NoteOutcome assessment, time point: selected time points span 52 to 79 weeks
  • NoteOutcome assessment, analysis set: mixed: randomized 1, safety 4
  • NoteData handling, input conversions: nonserious_only 6

Trial data

What each trial contributes. Arm rows give the arm value with its standard error, or events over participants; contrast rows give the hazard ratio (from event counts) on the analysis scale (log) against the trial's first row. Flags mark converted, combined or approximated inputs.
