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 the prevalence of lower urinary tract symptoms (LUTS) and genital symptoms among transgender men in Japan, and to evaluate their impact on daily life, including limitations resulting from concerns about toilet accessibility.

methodsWe conducted a cross-sectional, single-center survey of assigned-female-at-birth individuals aged 16 years or older who had been approved for gender-affirming hormone therapy at our gender center. A self-administered questionnaire included the Core Lower Urinary Tract Symptom Score (CLSS), vaginal and urethral symptom items, toilet use outside the home, preferences regarding male urinals, and activity restriction related to toilet access. Data were analyzed descriptively, and multivariable logistic regression analyses were performed.

resultsData from 322 participants (median age 33 years) were analyzed. Overall, 80% reported at least one LUTS, 46% reported at least one bothersome symptom, and 14% had a CLSS global quality-of-life (QOL) score of ≥ 4. Vaginal symptoms occurred in 13% of participants, and 2% reported post-micturition leakage. Most participants (62%) did not use male urinals but wished to use them. Activity restriction due to toilet-related concerns, defined as avoiding or limiting activities such as travel, shopping, or going to the cinema, was reported by 20%, and higher total CLSS was associated with both activity restriction and poor urinary-related QOL.

conclusionsLUTS and genital symptoms are common in young transgender men, and greater LUTS burden is linked to urinary-related QOL impairment and toilet-related activity restriction. These findings highlight the need for targeted clinical care and improved accessibility of public toilets for transgender men.
