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
purposeWe described our experience in the management of PUV at UNIOSUN Teaching Hospital, Osogbo, Osun State.
methodsThis was a retrospective analysis of patients with diagnosis of PUV carried out over a 4 year period (2019-2023). Demographic characteristics, clinical presentation, diagnosis and mode of therapeutic interventions were the variables analysed.
resultsA total of 17 patients with PUV were managed during the study period. Median age at presentation and surgery were 10 months (range 3.0-48.0) and 13 months (range 3.0-49.5), respectively. Most common presentation was poor urinary stream, 11 (64.7%). Mean PCV was 34.42%. Klebsiella aerogens was the predominant 9 (52.9%) organism isolated. A patient had prenatal USS diagnosis suggestive of PUV, majority (52.9%) had bilateral grade 1 V hydronephrosis at presentation. Voiding cystogram was diagnostic in 14 patients, (82.4%) while urethrocystoscopy was done in 14 (82.4%) patients. Median creatinine level were 116, 76.5 and 51.0 (micromol/l) pre- and post-catheterization and 1 month post-surgery, respectively. There was positive correlation between the age and post- surgery creatinine but a negative correlation between the PCV and grade of hydronephrosis. All patients had Mohans valvotomy. We had mortality in a patient from urosepsis. At 6 months-1 year follow-up, 15 patients had good urine stream with stable renal function.
conclusionEarly intervention assist in optimizing renal and bladder function and minimize risk of urosepsis. Where there is no facility for endoscopic valve ablation, Mohans valvotomy remains a viable treatment option.
