Development of a nomogram to predict risk factors for orchiectomy after testicular torsion in children.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Testicular torsion (TT) in children is a common urological emergency, and timely and accurate management is crucial for prognosis. Orchiectomy is one of the severe complications of this condition, and accurately predicting its risk is of great significance for clinical decision-making. This study aims to develop a nomogram to predict risk factors for orchiectomy after TT in children. This study retrospectively collected clinical data from 327 cases of TT at the Children's Hospital of Fudan University and 141 cases at Anhui Provincial Children's Hospital, which were classified into the training and validation cohorts, respectively. Multivariate logistic regression analysis was performed to identify independent predictors of orchiectomy in TT patients, and a nomogram was constructed. The model's effectiveness in both the training and validation cohorts was evaluated using the area under the receiver operating characteristic curve (AUC), calibration curves, and decision curve analysis (DCA). A total of 468 cases were included, of which 230 (49.15%) ultimately underwent orchiectomy. Duration of symptoms, neutrophil count, eosinophil count, degree of torsion, undescended testis(UDT), Testicular Workup for Ischemia and Suspected Torsion(TWIST) score grading, and ultrasound blood flow signal were identified as independent risk factors for orchiectomy in children with TT and were used to construct the nomogram. The AUCs of the nomogram were 0.93 (95% CI: 0.91-0.96) in the training cohort and 0.86 (95% CI: 0.79-0.92) in the validation cohort. The calibration curves demonstrated good agreement between predicted and observed values, and DCA indicated that the constructed nomogram had a high clinical net benefit. The nomogram developed in this study effectively predicts the risk of orchiectomy after TT in children, providing clinicians with a valuable decision-making tool. Future multicenter clinical studies are needed to optimize and validate the model's effectiveness.
