  1. IOP intraocular pressure, SBP systolic blood pressure, DBP diastolic blood pressure, BMI body mass index
  2. Cigarette smoking: number of cigarettes smoked per day
  3. Alcohol consumption: never or seldom = 0, several times per month = 1, several times per week = 2, every day = 3
  4. Regular exercise: no = 0; yes = 1
  5. Age, SBP (model 1) or DBP (model 2), number of cigarettes consumed per day, alcohol consumption (never or seldom = 0, several times per month = 1, several times per week = 2, everyday = 3), and regular exercise (no = 0; yes = 1) were added as independent
  6. *Age, BMI, number of cigarettes consumed per day, alcohol consumption (never or seldom = 0, several times per month = 1, several times per week = 2, every day = 3), and regular exercise (no = 0; yes = 1) were added as independent variables
