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
objectiveTo determine the diagnostic performance of tumor capsule contact length (TCCL) and to determine its optimal cut-off on prostate MRI to predict extra-capsular extension (ECE) at histopathology of radical prostatectomy specimen in patients with prostate cancer. MATERIALS AND
methodsAn electronic search of the PUBMED and EMBASE databases was performed until December 31, 2024 to identify studies analyzing TCCL as a predictor of ECE on prostate MRI. Pooled sensitivity and specificity of all studies were plotted in a hierarchical summary receiver operating characteristic plot and the risk of ECE was evaluated using bivariate random-effects meta-analysis. Meta-regression analysis for various TCCL cut-offs was performed.
resultsTwenty-three eligible studies were found. Reported sensitivity (between 47 - 94%) and specificity (between 46 - 88%) showed significant heterogeneity between studies, without evident threshold effect. Pooled sensitivity and specificity of TCCL for predicting ECE was 76.3% and 68.8% respectively with AUC of 0.787 for the summary ROC curve. Meta-regression analysis showed no significant difference in diagnostic performance according to various TCCL cutoffs, measurement methods, or ISUP grade distribution. Studies with 14 mm threshold had similar sensitivity (73%), but greater specificity (74% vs. 70%) and diagnostic odds ratio (8.3 vs. 6.5), when compared to 10 mm threshold.
conclusionTCCL on MRI has reasonable pooled sensitivity and specificity to predict ECE. While sensitivity remained moderately high for all TCCL thresholds, specificity at 14 mm (cutoff close to 15 mm suggested by PI-RADS v1.0) threshold was greater than that at 10 mm (cutoff suggested by PIRADS v2.1). This cutoff can be helpful in developing objective likelihood scores for ECE prediction on MRI.
