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
objectivesTo explore the value of a multiparametric MRI combined model based on morphology, hemodynamics, and apparent diffusion coefficient (ADC) in differentiating triple-negative breast cancer (TNBC) from non-triple-negative breast cancer (non-TNBC).
methodsA retrospective study was conducted on 213 breast cancer patients (64 TNBC, 149 non-TNBC). Morphological, hemodynamic, mean apparent diffusion coefficient (ADC), and relative apparent diffusion coefficient (rADC) features were compared. Feature selection was performed using LASSO, and a multiparametric combined model was constructed using logistic regression. Diagnostic performance was evaluated using receiver operating characteristic (ROC) curves and DeLong tests. Calibration and clinical utility were evaluated using the Hosmer-Lemeshow test, calibration curves, and decision curve analysis (DCA).
resultsTNBC tended to present as unifocal lesions with hyperintensity on T2WI. They also frequently showed cystic necrosis, peritumoral edema, and Type II/III curve patterns (all
conclusionsThe combined model - constructed based on multifocality/multicentricity, peritumoral edema, and the rADC1 value - can effectively predict TNBC preoperatively, has good discrimination, calibration, and clinical utility, and provides an important imaging reference basis for accurately identifying TNBC and formulating individualized diagnosis and treatment plans.
