*Gender was coded as follows: 0 = women, 1 = mixed, 2 = men
**CVD risk at baseline was coded as follows: 1 = Low CVD risk, 2 = Moderate CVD risk, 3 = existing CVDCHO: carbohydrate
CI: confidence interval
CVD: cardiovascular disease
E: energy
MUFA: monounsaturated fatty acid
PUFA: polyunsaturated fatty fat
SFA: saturated fatty acid
TC: total cholesterol
