  1. Linear regression models were used to estimate β and 95% CIs and adjusted for smoking, drinking, vigorous physical activity, pox ratio, creatinine level, energy intake, history of diabetes, hypertension, cardiovascular diseases, cancer, liver disease and dyslipidaemia
  2. aPCA is the method of principal component analysis and included the “Lower energyintake”, “Low vitamin A, C, K pattern” and “Vitamin B group” nutrient patterns
  3. bRRR stands for reduced rank regression and included the “High fat and low vitamin diet” pattern, which was related to obesity
