For this, a case-crossover study design, where patients who have experienced the outcome (cases) are a part of their controls by containing a period before the onset of the outcome. Additionally, a design based on person-day measurements, rather than individuals, was used for cases and controls. When comparing the group of cases (exposed to ASP/not exposed), we found: 127/578 vs. group controls (ASP exposed/unexposed): 547/3,968, and an OR=1.6 (95% CI:1.29) was obtained (-1.97; z= 4.31; p %U https://archivepp.com/article/high-levels-of-blood-lactate-associated-with-the-use-of-low-dose-aspirin-a-case-control-study-am6tsceddr5zz3r
