Figure 3. Multivariable-Adjusted Hazard Ratios and 95% CIs for Myocardial Infarction, Ischemic Stroke, and Hemorrhagic Stroke Across Sex-Specific Healthful vs Unhealthful Plant-based Diet Index Quartiles (n = 123 134).

All models used age as the underlying time variable and were adjusted for sex, body mass index, race and ethnicity, physical activity level, smoking status, alcohol intake, education level, energy intake, polypharmacy index, multimorbidity index, and aspirin use, stratified by region. For myocardial infarction analyses, models were further adjusted for polygenic risk score (coronary artery disease). For ischemic stroke analyses, models were further adjusted for polygenic risk score (ischemic stroke). For hemorrhagic stroke analyses, models were further adjusted for polygenic risk score (cardiovascular disease). hPDI indicates healthful plant-based diet index; HR, hazard ratio; uPDI, unhealthful plant-based diet index.
