Epidemiology survey and risk factor analysis of overactive bladder in children in Qingdao, China.

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
objectiveExplore the epidemiological characteristics and risk factors of overactive bladder (OAB) in children in Qingdao, China.
methodA stratified random cluster sampling method was adopted from 20 primary schools of Qingdao between September 2024 and June 2025. Data were collected through anonymous questionnaires, including basic information, lower urinary tract symptoms, Overactive Bladder Symptom Score, Pediatric Sleep Questionnaire (PSQ) and Strengths and Difficulties Questionnaire. Meanwhile, body mass index (BMI), history of nocturnal enuresis (NE), diaper use, urinary tract infection, constipation, and external genitalia development were collected.
results3200 questionnaires were distributed, with 2986 valid ones recovered, including 1492 boys and 1494 girls. The morbidity of OAB was 5.86% (175/2986), with 7.24% (108/1492) in boys and 4.46% (67/1494) in girls, and the difference was statistically significant (P < 0.001). The morbidity of children over 9-year-old (4.45%, 77/1683) and those under 9-year-old (7.52%, 98/1303) was statistically significant (P < 0.001). NE history, urinary tract infection history, constipation, excessive use of diapers, boy with phimosis or redundant prepuce were independent risk factors. The scores of emotional symptoms, conduct problems, hyperactivity symptoms, peer relationship problems, total difficulty score, and total PSQ score in the OAB group were significantly higher than those of the non-OAB group, with statistically significant differences (all P < 0.05).
conclusionsBoys and children under 9-year-old are at higher risk of OAB in Qingdao. History of NE, urinary tract infection, constipation, excessive use of diapers, and a boy with phimosis or redundant prepuce are the main independent risk factors. Meanwhile, OAB significantly affects children's mental health and sleep quality.
