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.
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 and factors associated with nocturia, defined as ≥ 2 times/night, among participants from the 2023 Japan Community Health Survey (JaCS 2023).
methodsUsing data from JaCS 2023, a nationwide online survey comprising 48 questionnaire items on lower urinary tract symptoms and daily life, 6210 participants aged 20-99 years were evaluated. Based on the definition of nocturia, participants were divided into Nocturia and Non-nocturia groups. The prevalence of nocturia was examined, and multivariable logistic regression analysis was performed to explore factors associated with nocturia by sex. In addition, subgroup analyses were performed for participants aged < 60 and ≥ 60 years.
resultsThe overall prevalence of nocturia was 27.1% in men (aged ≥ 40 years: 31.4%, aged ≥ 60 years: 39.8%, aged ≥ 80 years: 58.1%) and 17.8% in women (aged ≥ 40 years: 19.9%, aged ≥ 60 years: 24.7%, aged ≥ 80 years: 38.2%) and increased with age (p for trend < 0.0001). Age, performance status (PS) ≥ 1, hypertension, depression/anxiety, insomnia, benign prostatic hyperplasia (BPH), fecal incontinence, alcohol intake more than once a week, and erectile dysfunction (ED) in men, and age, PS ≥ 1, decreased walking speed, hypertension, and insomnia in women were independently associated with nocturia. Subgroup analysis showed that ED in all male groups and PS ≥ 1 in all female groups were significant factors.
conclusionsThe prevalence of nocturia increases with age. Age, PS ≥ 1, insomnia, and hypertension were significantly associated with nocturia in both men and women.
