Regression models with falls as dependent variable: Model 1 age and sex. Each fall-related chronic diseases, was tested as a risk factor adjusted for age and sex. Model 2 included all fall-related chronic diseases with a p value < 0.15 adjusted for age and sex and an OR >1. Model 3, including FRIDS and all fall-related chronic diseases from Model 2 with a p value < 0.15 adjusted for age and sex.
