1 · What the graph read from it

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.

Abstract

Elevated levels of oxidized phospholipids (OxPL) on plasminogen (OxPL-PLG) are associated with reduced time to fibrinolysis and reduced risk of cardiovascular events, but their effect on platelet function is unknown. We aimed to evaluate the association of OxPL-PLG with platelet surface marker expression, intrinsic and on‑dual anti-platelet (DAPT, aspirin plus clopidogrel)) platelet reactivity and cardiovascular events. OxPL-PLG levels were measured in pre-procedure blood samples in 2040 patients undergoing coronary angiography with or without PCI. The association of OxPL-PLG to pre-procedure and 24-hour platelet surface expression of CD62P, CD41 and PAC-1 and intrinsic and on-DAPT platelet reactivity in response to collagen and adenosine diphosphate (ADP) were assessed. The relationship of OxPL-PLG to myocardial infarction(MI)-free survival over a median 7-year follow-up was assessed using multivariable Cox regression models. Elevated levels of OxPL-PLG were significantly and inversely associated with age, male sex, severity of coronary obstruction, previous MI, PCI, and CABG. OxPL-PLG was inversely associated with platelet surface expression of CD41 (p < 0.001), CD62P (p = 0.0012) and PAC-1 (p < 0.001) at baseline and with CD41 (p = 0.001) and CD62P (p = 0.020) after DAPT. A significant inverse association was present between OxPL-PLG and intrinsic platelet reactivity in response to ADP (p < 0.001) at baseline but not after DAPT. OxPL-PLG was not associated with MI-free survival. In conclusion, elevated OxPL-PLG levels are independently associated with lower-risk clinical profile, less severe coronary disease, and reduced platelet activation and reactivity prior to DAPT. These findings suggest OxPL-PLG may modulate platelet activation and reactivity and warrant further mechanistic and clinical evaluation.
