Bladder height width ratio on voiding cystourethrogram as a predictor of future valve bladder in children with posterior urethral valve.
Article in Pediatric surgery international, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
BACKGROUND/
aimsPrompt and early treatment of valve bladder is known to improve renal outcome in patients with PUV. We hypothesized that bladder height width ratio (HWR) measurement on voiding cystourethrogram (VCUG) could predict development of valve bladder.
methodsAll patients who underwent primary PUV ablation and evaluated later with urodynamics were included. Valve bladder was suspected when there were daytime wetting, persistent hydroureteronephrosis, and elevated detrusor pressures on urodynamics. VCUGs were analysed for HWR: maximum height/width of bladder. ROC curve analysis was performed to identify HWR that could predict development of urodynamic abnormality.
resultsBetween 2012 and 2017, 102 patients were studied: median age at valve ablation 25 days (3-125 days); follow-up 5 years (3-7 years). The ROC curve comparing post-ablation HWR with occurrence of valve bladder showed a cut-off of 1.45 (AUC 0.93). HWR cut-off of 1.45 had a sensitivity of 89% and specificity of 84% in predicting future valve bladder. Detrusor overactivity was noticed on urodynamics in 41/55 (74%) of those with HWR > 1.45 compared 5/47 (11%) in those with HWR < 1.45 (p = 0.001).
conclusionBladder height width ratio on VCUG is a useful parameter to predict development of future valve bladder in children with PUV.
