  1. 1From Mantel-Haenszel extension chi-square test. Tertile 1: low pro-inflammatory properties, tertile 2: medium pro-inflammatory properties, and tertile 3: high pro-inflammatory properties
  2. Model 1: adjustment was made for age, sex, and energy (kcal/d). Model 2: additional adjustment was made for marital status, education, smoking, and physical activity. Model 3: adjusted for body mass index (BMI). Model 4: anti-psychotropic medicines, medical history of diseases, and stressful life events were additionally adjusted
