  • Adjusted for age, BMI, daily smoking, physical activity, education, alcohol consumption, diabetes and combined coffee habits.

  • β, regression coefficient, difference in total cholesterol (mmol/L) compared with the reference group of 0 cups per day.

  • *Test for interaction between sex and coffee consumption (as an ordinal variable).

  • BMI, body mass index; S-TC, serum total cholesterol.
