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
Thrombocytopenia, a common side effect of chronic liver disease (CLD), increases bleeding risk during invasive procedures. Thrombopoietin receptor agonists (TPO-RAs) offer an effective alternative to platelet transfusions. A systematic review and meta-analysis assessed the efficacy and safety of TPO-RAs in thrombocytopenia patients undergoing elective procedures. A systematic search (PubMed, Google Scholar, Cochrane Library, up to August 2024) evaluated perioperative thrombopoietin receptor agonists in patients with thrombocytopenia undergoing elective procedures. Primary and secondary outcomes included platelet count ≥50 x 10^9/L, bleeding/thrombotic events, platelet transfusions, adverse effects, rescue treatment, discontinuation, death, and serious adverse effects, analyzed via random-effects model. This meta-analysis synthesized evidence from nine trials and 1,409 patients (819 TPO-RAs vs 590 placebo; mean age ~59 years). TPO-RAs significantly increased the likelihood of achieving platelet counts ≥50×10⁹/L compared with placebo (RR 3.93, 95% CI 2.24-6.90; p<0.00001). They also reduced the need for preoperative platelet transfusions (RR 0.34, 95% CI 0.27-0.44; p<0.00001) and lowered the risk of surgical bleeding (RR 0.64, 95% CI 0.49-0.85; p=0.002). In contrast, no statistically significant differences were observed for thrombotic events (RR 1.24, 95% CI 0.57-2.67; p=0.59), treatment-emergent adverse events (RR 0.99, 95% CI 0.89-1.09; p=0.83), study drug discontinuation (RR 0.74, 95% CI 0.32-1.70; p=0.47), rescue treatment use (RR 0.82, 95% CI 0.34-2.03; p=0.67), all-cause mortality (RR 1.23, 95% CI 0.35-4.35; p=0.75), or serious adverse events (RR 1.13, 95% CI 0.70-1.84; p=0.62). TPO-RAs raise platelet counts and reduce transfusions in CLD patients undergoing invasive procedures. However, close monitoring for thrombotic risks is necessary, and further research is needed to optimize dosing.
