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 potential of dynamic contrast-enhanced MRI (DCE-MRI) histogram analysis for predicting overall survival (OS) in epithelial ovarian cancer (EOC) patients.

methodsThis retrospective study included 155 patients with EOC who underwent pretreatment DCE-MRI. Histogram features extracted from DCE-MRI parametric maps were selected using least absolute shrinkage and selection operator (LASSO) Cox regression, with selection stability assessed across 200 bootstrap replicates. Clinical, imaging, and combined models were developed using Cox regression and random survival forest (RSF). Apparent concordance indices (C-indices) were calculated and corrected for optimism using 100 bootstrap resamples with fixed predictor sets. Exploratory Kaplan-Meier analyses assessed risk-group separation, and SHapley Additive exPlanations (SHAP) analysis was used for model interpretation.

resultsMedian OS was 54 months. The 10th percentile of K
