Predictors of testicular salvage failure in pediatric testicular torsion: a retrospective analysis of clinical and imaging risk factors.
Article in Pediatric surgery international, 2025. 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
objectivesThis study aimed to construct preoperative nomograms for predicting testicular necrosis in pediatric patients with testicular torsion (TT).
methodsThis retrospective study analyzed clinical data from 176 patients diagnosed with TT at the Department of Pediatric Surgery, Ningxia Medical General Hospital, between January 2010 and January 2023. To identify independent risk factors for testicular necrosis, both univariate as well as multivariate logistic regression analyses were used. A predictive nomogram model was then developed based on the coefficients derived from multivariate regression analysis. A receiver operating characteristic (ROC) curve analysis and calibration plot were employed to evaluate the performance of the model.
resultsSurgical management included orchiopexy in 55 patients (31.4%) and orchiectomy in 121 patients (68.6%). Multivariate analysis identified five independent predictors of testicular necrosis: symptom duration, torsion severity (≥ 360°), absence of testicular blood flow on Doppler ultrasound, heterogeneous testicular echogenicity, and an elevated preoperative platelet-to-lymphocyte ratio (PLR). Internal validation demonstrated strong discriminative performance of the nomogram, with the area under the ROC curve values of 0.948 for the training cohort and 0.910 for the validation cohort. The calibration plots demonstrated a strong concordance between predicted probabilities and observed outcomes.
conclusionThese findings highlight duration of onset, degree of TT, ultrasound characteristics (vascularity loss and heterogeneous echotexture), and systemic inflammatory markers (PLR) as key preoperative indicators of testicular viability. The proposed nomogram serves as an evidence-based tool to guide intraoperative decisions on testicular preservation or resection.
