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
Objective: Assessment of disease-free survival (DFS) in triple-negative breast cancer (TNBC) using habitat analysis of preoperative DCE-MRI subtraction maps. Methods: This study retrospectively collected consecutive patients with pathologically confirmed triple-negative breast cancer from January 2019 to January 2025 at our institution for evaluation. Ratio maps of [(peak enhancement-unenhanced period)/unenhanced ROI] for wash-in ratio map, [(peak enhancement-delayed period)/enhanced ROI] for washout ratio map were obtained by DCE subtraction maps. Habitat was calculated based on the clustering of the two subtraction maps ratio maps, and intratumoral heterogeneity (ITH) was calculated based on the proportion of each cluster. Recurrence of TNBC was determined using Kaplan-Meier survival analysis, and multivariable Cox regression analyses were used to identify independent risk factors for TNBC recurrence. Result: A total of 145 patients with triple-negative breast cancer were finally enrolled, of whom 29 patients experienced recurrence. The results of DCE habitat analysis showed that the habitat ITH was higher in the high-risk recurrence group than that in the low-risk recurrence group (0.59 ± 0.14 vs. 0.42 ± 0.22, Conclusion: Habitat analysis of preoperative DCE-MRI subtraction maps contributes to the prognostic assessment of TNBC.
