Multivariate analysis (n 7985)
OR: Odds Ratio, derived from mixed-effects logistic regression models, adjusted for:
Model 1: demographic and socioeconomic factors.
Model 2: factors present in model 1 + diet and prevalence of cardiovascular risk factors.
Model 3: factors present in model 2 + protective factors in the diet and health care resources.
