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
Background: Breast cancer (BC) is the most prevalent malignant tumor among women worldwide, significantly impacting women's health and lives. The accurate assessment of axillary lymph node (ALN) status is critical for BC staging, treatment planning, and the evaluation of overall survival outcomes. This study aimed to explore the relationship between preoperative ultrafast dynamic contrast-enhanced magnetic resonance imaging (UF-DCE MRI) parameters and ALN metastasis in patients with mass-type invasive ductal carcinoma (IDC) of the breast, and to construct a nomogram model for predicting ALN metastasis. Methods: Preoperative UF-DCE MRI images and medical records of 96 breast IDC patients (38 with ALN metastasis, 58 without) confirmed by pathology were retrospectively analyzed. Conventional MRI features, UF-DCE MRI parameters, DCE parameters, and clinical features were evaluated. Receiver operating characteristic (ROC) curves and nomograms for univariate parameters and combined diagnostic efficiency were constructed. Results: Time-to-enhancement (TTE), time-to-peak (TTP) after enhancement, and time to center of maximum slope (TTMS) were significantly lower in the ALN metastasis group (10.05±4.91 Conclusions: Multiple UF-DCE MRI parameters can predict ALN metastasis in patients with mass-like breast IDC before operation. The nomogram model combined with clinical and UF-DCE MRI parameters can better assist clinicians in making personalized treatment plans for patients.
