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

purposeTo identify predictors of treatment success after urethral botulinum toxin A (100 U) injection in women with video-urodynamic study (VUDS)-diagnosed non-neurogenic dysfunctional voiding (DV), and to develop a nomogram for individualized clinical prediction.

methodsWe retrospectively reviewed 398 women with VUDS-confirmed non-neurogenic DV treated with urethral botulinum toxin A at a tertiary center. Baseline demographics and urodynamic variables were compared between responders (Global Response Assessment [GRA] ≥ 2 at 3 months) and non-responders (GRA < 2). Predictive modeling used multivariate logistic regression with stepwise selection. The entire cohort was randomly split into a training set (70%) for model development and a test set (30%) for internal validation. Model discrimination was evaluated by area under the receiver operating characteristic curve (AUC), and a nomogram was constructed from independent predictors.

resultsAt 3-month follow-up, 186 patients (46.7%) were classified as responders. Responders had significantly fewer prior Botox injections, lower bladder sensation thresholds, higher detrusor pressure at Qmax (Pdet), higher maximum flow rate (Qmax), greater voided volume, lower cystometric bladder capacity, higher voiding efficiency, and lower post-void residual (PVR). Multivariate analysis identified older age (OR: 1.025), higher Pdet (OR: 1.029), and lower PVR (OR: 0.989) as independent predictors of success. The model showed excellent discrimination in training (AUC = 0.847) and test (AUC = 0.871) sets. A nomogram was developed for individualized risk estimation.

conclusionOlder age, higher Pdet, and lower PVR independently predict successful response to urethral botulinum toxin A in women with non-neurogenic DV. This nomogram may guide personalized counseling and treatment decisions.
