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

objectivesTo investigate real-world practices in transurethral surgeries for bladder pain syndrome (BPS) and interstitial cystitis (IC) in Japan, with a focus on procedural characteristics of hydrodistension (HD) and transurethral elimination of Hunner lesions (TUEH).

methodsAn internet-based questionnaire was sent to all members of the Society of Interstitial Cystitis of Japan in November 2024. The survey inquired about institutional characteristics, the number of procedures performed in the previous 12 months, and detailed surgical techniques. BPS was defined by the absence of Hunner lesions, and IC by their presence. Responses were analyzed to describe procedural patterns and compare practices between HD and TUEH.

resultsOf 205 eligible members, 86 responded (response rate: 42%). Among them, 52 had performed HD for BPS and 67 had performed TUEH for IC within the study period. Most surgeons distended the bladder to a preset pressure of ≤ 80 cm H

conclusionsThis nationwide survey highlights contemporary surgical practices for BPS and IC in Japan. These findings may help clinicians evaluate and refine their own approaches to transurethral interventions for these complex conditions.
