Probabilities are based on a Cox model that adjusts for age, gender, race/ethnicity, education, smoking, physical activity and energy intake. Models include interaction terms for baseline dietary scores and weight category. Separate models were developed for each dietary pattern. Weight categories were based on BMI (normal: 18.5–<25 kg/m2; overweight: 25–<30 kg/m2; obese: ≥30 kg/m2).
p Values for interaction terms for quintiles of Mediterranean diet and weight category are: Q2-overweight, 0.626; Q2-obese, 0.159; Q3-overweight, 0.008; Q3-obese, 0.006; Q4-overweight, 0.250; Q4-obsese, 0.408; Q5-overweight, 0.367; Q5-obese, 0.366. p Values for interaction terms for quintiles of Healthy Eating Index and weight category are: Q2-overweight, 0.227; Q2-obese, 0.961; Q3-overweight, 0.411; Q3-obese, 0.974; Q4-overweight, 0.304; Q4-obsese, 0.164; Q5-overweight, 0.726; Q5-obese, 0.381. p Values for interaction terms for quintiles of DASH and weight category are: Q2-overweight, 0.486; Q2-obese, 0.090; Q3-overweight, 0.733; Q3-obese, 0.974; Q4-overweight, 0.344; Q4-obsese, 0.920; Q5-overweight, 0.482; Q5-obese, 0.411.
