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

purposeThis multicenter study aimed to identify risk factors for postoperative complications following tubularized incised plate urethroplasty (TIP) in hypospadias patients and develop a clinical prediction model.

methodsRetrospective data from 17 tertiary centers (2018-2021) were analyzed. INCLUSION CRITERIA: primary TIP surgery with complete anatomical and follow-up data. EXCLUSION CRITERIA: prior urethral surgery, genetic disorders, or incomplete records. Multivariate logistic regression identified independent predictors. A nomogram model was constructed and internally validated using bootstrapping (1000 resamples). Discrimination (AUC) and calibration (Hosmer-Lemeshow test) were assessed.

resultsAmong 493 patients (median follow-up: 42 months), the complication rate was 23.7% (117/493), including urethrocutaneous fistula (17.6%), stricture (6.5%), and diverticulum (2.8%). Independent predictors were: post-incision urethral plate width (OR: 0.01, 95% CI 0-0.05), glans width (OR: 0.81, 95% CI 0.66-0.98), and urethral defect length (OR: 1.47, 95% CI 1.00-2.16). The nomogram demonstrated moderate discrimination (AUC: 0.723, 95% CI 0.668-0.777) and good calibration (Hosmer-Lemeshow P = 0.382).

conclusionA clinical prediction model incorporating post-incision urethral plate width, glans width, and urethral defect length showed acceptable predictive accuracy for TIP complications.
