Abbreviations: RERI, relative excess risk due to interaction; S, synergy index. Joint effect of dietary inflammatory index (DII) and smoking status, on the risk of first myocardial infarction (MI) in a men b women. Odds ratios (OR) were estimated from multiple regression models adjusted for total energy intake, total serum cholesterol, systolic blood pressure, body mass index (BMI), diabetes, and postsecondary academic education. The calculations of RERI and S were performed comparing daily smokers/non-smokers and low DII/high DII
