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 evaluate the occurrence and timing of metachronous contralateral testicular torsion (CLTT) in patients with testicular torsion (TT) managed without contralateral orchiopexy (CLOP).

methodsWe retrospectively reviewed patients who underwent emergency TT surgery without CLOP at our hospital between April 2013 and April 2025. Patients with less than 6 months of follow-up, extravaginal torsion, or prior scrotal surgery were excluded. Primary outcomes included CLTT occurrence and time to CLTT.

resultsOf 40 patients surgically treated for TT, 24 met inclusion criteria. Median age at surgery was 14.0 years; 75.0% had left-sided TT. A bell-clapper deformity on the affected side was identified in 33.3%. Nineteen patients underwent orchiopexy, and five underwent orchiectomy. The median follow-up duration was 75.3 months. CLTT occurred in 1 of 24 patients (4.2%; 95% CIs, 0.1-21.1%) at 55.3 months after the initial surgery. The patient experienced the initial TT at age 16 years and developed CLTT at age 21 years.

conclusionCLTT can develop several years after the initial episode of TT, and it may occur in adulthood when CLOP is not performed at the time of adolescent onset. However, the small sample size and descriptive design preclude definitive conclusions.
