Subgroup analyses of the association between plasma sTREM2 and the primary outcome. The values below Q1–Q3 and Q4 were patients experiencing death or cardiovascular events, n (%). Hazards ratios (HRs) were calculated for higher plasma sTREM2 levels (≥ 651.60 pg/mL) after adjustment for the same variables as model 2 in Table 2, except for the stratified variable. CI indicates confidence interval; NIHSS indicates National Institutes of Health Stroke Scale; and hsCRP indicates high-sensitivity C-reactive protein
