Hazard ratio for association of combined medication use with AD diagnosis after TBI. a Patients taking two combined medications were compared to those taking both statins and metformin using the Cox model. The ACEI and statin group showed the most stable reduction in hazard ratio for developing dementia with possible AD. b Hazard ratio of same group of patients was analyzed using the Cox model with a propensity score adjusted for demographic factors. c Patients taking two combined medications were compared to those taking no medication using the Cox regression model. d Hazard ratio from the same group of patients was analyzed using the Cox regression model with a propensity score adjusted for demographic factors
