1 · What the graph read from it

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.

2 · The registry

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

purposeThis study aimed to compare the efficacy and safety of combination therapy consisting of α-blockers and different phosphodiesterase type 5 inhibitors for lower urinary tract symptoms (LUTS) by performing a network meta-analysis.

methodRelevant articles were retrieved from the Cochrane Library, PubMed, and EMBASE databases. Bayesian network meta-analyses were performed with a random-effect model to compare the efficacy and safety of combination therapy with α-blockers and phosphodiesterase-5 inhibitors for LUTS. The odds ratio (OR), mean difference (MD) and surface under the cumulative ranking curve (SUCRA) were calculated with the GeMTC R package.

resultsTwenty randomized trials with 4131 patients were included in this network meta-analysis. Based on the SUCRA values, vardenafil (10 mg) combined with α-blockers ranked first, first and sixth; sildenafil (25 mg) combined with α-blockers ranked second, third and first; and tadalafil (20 mg) combined with α-blockers ranked third, second and fourth in IPSS, post void residual, and maximum flow rate, respectively.

conclusionsCombination therapy with α-blockers and phosphodiesterase-5 inhibitors was effective and well tolerated for LUTS. For men who prioritize high efficacy, vardenafil (10 mg) combined with α-blockers seems to be the treatment of choice. For men wishing to optimize minimally invasive treatment, sildenafil (25 mg) and tadalafil (20 mg) combined with α-blockers appears to have a possible advantage in terms of avoiding adverse effects.
