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

Objective: The objective of this study is to evaluate the correlation between erectile dysfunction (ED) and lower urinary tract symptoms (LUTSs) using the International Index of Erectile Function-5 (IIEF-5) and the International Prostate Symptom Score (IPSS). Methods: An online survey was conducted among 4800 Japanese men using the International Index of Erectile Function-5 (IIEF-5), International Prostate Symptom Score (IPSS) and Overactive Bladder Symptom Score (OABSS). After excluding one incomplete response, data from 4799 participants were analysed. Participants were grouped by ED severity according to IIEF-5 score. The total and subcategory scores of the IPSS and OABSS were compared among the groups. LUTSs were categorized as post-micturition, storage, voiding symptoms and incontinence. An additional analysis was conducted by age group: younger (40s-50s) and older (≥70s). Results: Lower ED severity was associated with significantly lower IPSS and OABSS total scores ( Conclusion: ED severity is positively correlated with LUTS severity, particularly voiding symptoms and incontinence. This relationship was more prominent in younger men.
