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
Introduction We aimed to assess whether partial hepatectomy has an influence on conventional and speckle tracking parameters on echocardiography in living liver donors in the early postoperative period. Methods This study was a retrospective study to investigate the cardiac effects of liver donation after the transplant operation in a high-volume liver transplant center. Ninety living liver donors were included in the study. The echocardiographic images were obtained from 90 living liver donors before and five to seven days after the operation. The echocardiographic examinations were evaluated with a Philips Epiq 7 ultrasound system (Philips Ultrasound; Bothell, WA, USA) by experienced cardiologists in accordance with the recommendations of the American Society of Echocardiography. These included M-mode, two-dimensional imaging, tissue Doppler assessment at the septal and lateral mitral annulus, and strain imaging in all patients at rest in the left decubitus position. The changes in echocardiographic parameters in living liver donors were analyzed. Paired T-test was used to assess significant differences. Results The left ventricular (LV) global longitudinal strain (GLS), right ventricular (RV) GLS, and RV free wall LS, reservoir phase of left atrial strain (LAS-r), conduit phase of LAS (LAS-cd) did not show significant changes after the operation (for all, p>0.05). However, the absolute atrial contraction phase of LAS (LAS-ct) mean value increased significantly (14.2±8.8 vs 16.6±8.3, p=0.025) postoperatively. Among the conventional echo parameters, isovolumic relaxation time (IVRT) and the E/A ratio demonstrated notable postoperative alterations. The mean IVRT (87.3 ± 22.4 vs. 80.8 ± 18.1, p=0.014) and E/A ratio (1.5 ± 0.5 vs. 1.3 ± 0.3, p=0.012) exhibited a postoperative decline. Conclusions To the best of our knowledge, our study is the first to evaluate the effect of partial hepatectomy on cardiac functions by echocardiography in living liver donors, and there was no deterioration in the functions of both the ventricles and left atrium.
