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
Accurate segmentation of renal anatomical structures is essential for informed clinical decision-making in nephropathology, supporting precise diagnosis, treatment planning, and longitudinal monitoring of kidney diseases. In this work, we propose an Edge-Aware U-Net architecture with Boundary-Sensitive Optimization, specifically designed to address the challenges of fine anatomical boundary delineation in histopathological images. Comprehensive benchmarking against state-of-the-art models including U-Net, Attention U-Net, and ResUNet demonstrates robust quantitative performance alongside strong potential for clinical deployment. The proposed model achieves superior boundary preservation, reflected by a high structural similarity index (SSIM: 0.9473), while maintaining computational efficiency with an average inference time of 52 ms per image. It further outperforms existing methods across key image quality metrics, including PSNR (17.269 dB), MAE (0.0266), and RMSE (0.0321). Clinical validation indicates statistically significant improvements in glomerular detection (
