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
Percutaneous valve implantation or surgical replacement with mechanical or biological valves are standard therapies for severe valvular heart diseases. Prosthetic valve thrombosis, though rare, is a serious complication, particularly with mechanical prostheses. This study aimed to investigate the predictive value of platelet volume parameters, including mean platelet volume (MPV), platelet distribution width (PDW), and platelet-large cell ratio (P-LCR), for valvular thrombosis risk in patients undergoing valve replacement therapy. A retrospective cross-sectional study was conducted from May 2002 to May 2020, involving 108 patients with a history of mitral or aortic valve replacement and valvular thrombosis, and 216 controls with a history of valve surgery without valvular malfunction. PDW was significantly associated with an increased risk of thrombosis after adjusting for confounders, while MPV showed a clinical difference but did not reach statistical significance. P-LCR did not exhibit a significant association. These findings suggest PDW as a potential predictor of valvular thrombosis in such patients. The ease of measuring platelet volume parameters suggests their utility in routine hematological analysis for identifying patients at higher risk of valvular thrombosis post-replacement surgery. Further studies are warranted to validate these findings and explore additional laboratory markers, such inflammatory markers, for thrombotic risk assessment in this population.
