Cox regression models to assess the relative risk of diabetes by allocation group, estimating the hazard ratios and their 95% CIs were performed.
Adjusted for baseline energy intake, BMI, waist circumference, physical activity, smoking status, fasting serum glucose, use of lipid-lowering drugs, Mediterranean diet score, and weight change during the study.
Adjusted for the same variables as †, except the variable of interest.
Excluding 2n nonrandomized partners. P for interaction (MedDiet * sex): 0.382; P for interaction (MedDiet * age): 0.218; P for interaction (MedDiet * BMI): 0.729; P for interaction (MedDiet * fasting glucose): 0.793. MedDiet, Mediterranean diet; VOO, virgin olive oil.
