Vibegron, mirabegron, and other add-on therapies for persistent overactive bladder symptoms in α1-blocker-treated men with benign prostatic hyperplasia: a systematic review and Bayesian network meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo compare the efficacy and safety of vibegron, mirabegron, and other add-on therapies for overactive bladder (OAB)/storage symptoms persisting despite α1-blocker treatment in men with benign prostatic hyperplasia (BPH), focusing on the indirect vibegron-mirabegron comparison.
methodsWe searched PubMed, Web of Science, CENTRAL, ClinicalTrials.gov, and Google Scholar through 27 August 2026. Bayesian random-effects network meta-analyses used mean differences for continuous outcomes and odds ratios (ORs) for study-reported treatment-period adverse events (AEs). Confidence was appraised with CINeMA.
resultsEighteen trials were included; 16 contributed quantitative data. Versus control, vibegron reduced micturitions per 24 h (mean difference - 0.81, 95% credible interval [CrI] - 1.31 to - 0.38) and urgency episodes per day (- 0.96, - 1.57 to - 0.34), and mirabegron reduced micturitions by 0.46 per 24 h (- 0.88 to - 0.02). For vibegron versus mirabegron, indirect estimates were - 0.35 micturitions per 24 h (- 1.05 to 0.26) and - 0.52 urgency episodes per day (- 1.33 to 0.35), with all 95% CrIs including the null value. Reported AE odds were also inconclusive versus mirabegron (OR 1.50, 0.69 to 3.14), and AE definitions varied. Confidence was moderate for vibegron versus control on micturitions and urgency and low for indirect and safety estimates.
conclusionVibegron reduced micturition frequency and urgency versus control and may be considered an add-on option in α1-blocker-treated men. The vibegron node rested on two trials, and no advantage over mirabegron was established; posterior probabilities above 0.8 do not indicate superiority when credible intervals include the null value.
