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

Vacuum erection device (VED) as one of the approved therapies for erectile dysfunction (ED) is widely used. However, available evidence of VED efficacy on refractory ED, a condition often unresponsive to phosphodiesterase type 5 (PDE5) inhibitors, is limited. A literature search was performed using PubMed, EMBASE, and the Cochrane Library to identify all clinical trials up to December 2024. The primary outcome was efficacy defined as successful intercourse or intercourse satisfaction after VED intervention, and the secondary outcome was the incidence of most common side effects. The pooled rate with 95% confidence intervals (CI) was selected as the effect size. Heterogeneity was assessed by Cochran's Q test and the I
