Automated deep learning for real-time focal liver lesions detection in ultrasound videos a multicenter study.
Article in NPJ digital medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Early detection of focal liver lesions (FLLs) is crucial for clinical practice, but ultrasound performance heavily depends on operator experience. We developed Auto-DFLLs, an automated deep learning model based on ResNet and FPN architectures to detect FLLs in ultrasound videos. It was trained and validated on 5258 prospectively collected videos from three hospitals. On internal validation, Auto-DFLLs achieved an AP50 (average precision at IoU = 50%) of 0.7772, Pr70 (precision at 70% recall) of 0.7967, and FP70 (false positives at 70% recall) of 3.4688. Validation study showed that Auto-DFLLs significantly improved junior sonographers' detection (AFROC-AUC: 79.52 vs. 71.55, P = 0.021) and enhanced senior sonographers' performance (AFROC-AUC: 78.64 vs. 74.57, P = 0.0366), especially for small lesions (< 10 mm, P = 0.034). Auto-DFLLs maintained stable detection across different lesion size, echogenicity, location, and ultrasound equipment from different manufacturers. Auto-DFLLs reduces operator-dependent variability and offers a reliable assistive tool for real-time FLLs screening, particularly valuable in resource-limited areas.
