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

purposeTesticular torsion is a prevalent scrotal emergency associated with a significant risk of testicular loss, and there is no reliable scoring system available to assess the likelihood of orchiectomy following testicular torsion.

methodsClinical characteristics and surgical data of patients with testicular torsion from January 2015 to May 2024 were gathered from National Center for Children's Health (NCCH) and the Children's Hospital of Capital Institute of Pediatrics (CIPCH). Independent risk variables for testicular resection were evaluated by logistic regression analyses, leading to the establishment of a nomogram. The performance of the nomogram was assessed and validated using AUC, C-index, calibration curves, and DCA. Patients were classified based on their risk score obtained from the nomogram for clinical application.

resultsA total of 387 patients were included. Risk factors were identified by multifactorial analysis: symptoms duration, testicular blood flow, degree of torsion, and cryptorchidism. A nomogram exhibits an area under the ROC curve of 0.9305 and a C-index of 0.9310. A scoring system was developed accordingly, categorising patients into four groups; 88.7% of patients in the super-low and low-risk categories preserved their testes, while 78.6% in the super-high and high-risk categories underwent testicular resection.

conclusionThe strong concordance between predicted and actual outcomes suggests the model's utility in clinical decision-making. The nomogram demonstrates robust calibration and differentiation capabilities.
