a) M-CHIP and all classes of mCAs were associated with increased risk of all-cause-mortality but L-CHIP did not increase the risk of mortality. b) Only M-CHIP, A-mCA and U-mCA were associated with mortality unrelated to hematologic malignancies. c) M-CHIP is associated with increased risk of coronary artery disease. No other CH categories were associated with risk of coronary artery disease. (a-c) Data are presented as hazard ratio and 95% confidence intervals, computed by using Cox proportional hazards model adjusting for age, sex, smoking, genetic ethnic ancestry, and genetic principal components 1–5. HR, hazard ratio; CI, confidence interval; VAF, variant allele fraction; CF, cell fraction.
