Risk factors for inferior right hepatic vein occlusion following right lobe living donor liver transplantation: a single-center experience with 240 cases.

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
This study aims to analyze the early and long-term outcomes of inferior right hepatic vein (IRHV) reconstruction and identify risk factors associated with IRHV occlusion in right lobe living donor liver transplantations (RL-LDLT). This retrospective cohort study included patients who underwent RL-LDLT with IRHV reconstruction at Institution between January 1, 2021, and December 31, 2023. Data were collected from hospital records, surgical notes, anesthesia records, radiology reports, and patient files. Patients were divided into three groups based on IRHV patency status: patent and early occluded, and late occluded. Preoperative, intraoperative, and postoperative data were analyzed. A total of 204 patients were included in the study. The mean follow-up period was 750.34 ± 364.3 days. IRHV remained patent in 69.61% (n = 142) of patients, whereas 30.39% (n = 62) experienced IRHV occlusion. Early IRHV occlusion (within 30 days) occurred in 52 patients (83.9% of occluded cases). In early occluded cases, the mean IRHV diameter was significantly smaller (4.92 ± 1.61 mm) compared to the open group (6.02 ± 1.72 mm; p < 0.001). ROC analysis identified an IRHV diameter ≤ 5 mm as a cutoff value for predicting occlusion risk (AUC = 0.704; p < 0.001). In long-term follow-up, another 10 patients' IRHV occluded, late occluded patients were significantly younger (40.63 ± 14.56 vs. 53.21 ± 13.54 years; p = 0.005), had lower body weight (64.30 ± 13.02 vs. 76.55 ± 12.78 kg; p = 0.004), and lower BMI (22.72 ± 3.78 vs. 27.43 ± 4.07 kg/m
