Increased Platelet Aggregation in Adults After Orthotopic Liver Transplantation Indicates Higher Probability of Early Postoperative Survival.
Article in Annals of transplantation, 2023. 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
BACKGROUND Studies have shown that increased platelet aggregation in patients with decompensated cirrhosis indicates higher risk of further decompensation and death, but studies on the association between platelet aggregation function and early postoperative survival in orthotopic liver transplantation (OLT) patients are rare. We conducted a retrospective study to investigate whole-blood platelet aggregation during the perioperative period of OLT patients and its association with clinical outcomes. MATERIAL AND METHODS Adult patients who underwent OLT between January 1 and April 30, 2021 were retrospectively reviewed. Laboratory test results indicating primary hemostasis were analyzed. The generalized linear model was used to investigate the association between primary hemostasis parameters and survival. RESULTS A total of 256 patients were enrolled. The median platelet count (PLT) was 61.5 (39.5-106.3)×109/L before transplantation. The median MA value was 43.1 (34.5-56.2) mm. From the 1st to the 3rd day after transplantation, PLT and MA both indicated a significant decrease. Two weeks after transplantation, PLT rose to 143.0 (85.0-209.0)×10⁹/L, and the MA value rose to 56.7 (52.2-62.7) mm. On multivariate analysis, PLT at 1 week after transplantation (OR: 1.07; P=0.006) and MA value (OR: 1.12; P=0.003) were independently associated with outcome. The AUROC of the model combined with MA value, MELD score, and age was 0.945 (95% CI: 0.911-0.978). CONCLUSIONS The change in primary hemostasis during the early postoperative period of adult OLT is mainly characterized by the increase of platelet count and function 14 days after transplantation. Higher PLT was associated with higher survival at 14 days after transplantation, while a higher PLT ratio was associated with survival at 3 months after transplantation. Based on comprehensive consideration, the model combined with MA value, MELD score, and age more reliably indicated the associated with early survival after transplantation.
