  1. FA fatty acid, n number of subjects, SBP systolic blood pressure, DBP diastolic blood pressure, CI confidence interval, T 3 the upper tertiles, T 1 the bottom tertiles
  2. aInitial model was adjusted for age, gender, BMI and hypertension
  3. bModel 1 was adjusted for covariates in the initial model plus smoking, alcohol intake, education, profession, exercise, and salt intake
  4. cModel 2 was adjusted for covariates in the model 1 plus family history, heart rate, triglyceride, total cholesterol and fasting blood-glucose level
  5. d P for trend was estimated by a multiple regression model, with ordinal numbers 0–2 assigned to tertile categories of each fatty acid
