Table 4.

Cox Proportional Hazard Ratios for incidence of AD for subjects with MCI at the 1^st evaluation by MeDi score. Adjusted models include slightly lower number of subjects because of missing data in some of the covariates. Adjusted models simultaneously control for cohort, age, gender, ethnicity, education, APOE genotype, caloric intake, body mass index and time between 1^st dietary and 1^st cognitive assessment.
