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
purposeTo validate the performance of three multiparametric quantitative sequences, including amide proton transfer-weighted (APTw) MRI, diffusion kurtosis imaging (DKI) and apparent diffusion coefficient (ADC), in the enhancement of biopsy decision-making in patients with Prostate Imaging-Reporting and Data System (PI-RADS) core of 3-4. MATERIALS AND
methodsA total of 96 participants who scored as PI-RADS 3-4 according to PI-RADS v2.1 and pathologically confirmed were enrolled. The mean of APT, ADC, mean diffusivity (MD) and mean kurtosis (MK) values were acquired by two radiologists and a senior radiologist. The univariate and multivariate logistic regression analyses were performed for parameters selection. Receiver operating characteristic (ROC) analysis was employed to assess the performance of models. The Delong test was applied to compare the area under the ROC curves (AUCs) between models. The proportion of unnecessary biopsies avoided (specificity) and csPCa missed (1-sensitivity) were calculated for each model.
resultsIn this PI-RADS 3-4 cohort, the AUCs for the diagnosis of csPCa were 0.730 (95%CI: 0.626, 0.834), 0.682(95%CI: 0.562, 0.802), 0.610(95%CI: 0.482, 0.739) and 0.706(95%CI: 0.593, 0.819) for APT, MD, MK and ADC values, respectively. The combined model yielded the significantly higher AUC of 0.851 (95%CI: 0.767, 0.934) (P < 0.05), and achieved a best trade-off between missing csPCa and avoiding unnecessary biopsy than other models (Youden = 0.615).
conclusionA novel diagnostic model incorporating APTw-MRI, DKI and ADC has been shown to provide incremental diagnostic value in stratifying biopsy necessity for patients with PI-RADS 3-4 lesions.
