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 develop and validate a Computed Tomography (CT) -based nomogram for distinguishing fresh from old osteoporotic vertebral compression fractures (OVCFs), with magnetic resonance imaging (MRI) as the reference standard.

methodsIn this retrospective study, OVCF patients from The First Affiliated Hospital of Chongqing Medical University (August 2022-December 2023) were analyzed. Modified CT window parameters (width: 400; level: 200) were applied to quantify vertebral features, including CT values, height reduction, endplate integrity, trabecular sparsity, Schmorl's nodes, and high-density shadows. Predictive variables were selected via univariate and multivariate logistic regression, followed by nomogram construction. Model performance was assessed using receiver operating characteristic (ROC) curves (area under the curve, AUC), calibration plots, Hosmer-Lemeshow testing, and decision curve analysis (DCA). 10-fold cross-validation was used to evaluate the generalization performance of the model.

resultsThe nomogram incorporated seven imaging biomarkers, achieving AUCs of 0.941 (training cohort) and 0.974 (validation cohort). The calibration accuracy was assessed using the Hosmer-Lemeshow test (χ²=3.30, P = 0.95). DCA demonstrating significant clinical utility across probability thresholds. In cross-validation, the mean AUC on the validation sets was 0.911 ± 0.080 (mean ± standard deviation).

conclusionThe proposed CT-based nomogram achieved adequate performance in identifying fresh and old OVCFs.
