Probability of combined MCI or AD (MCI + AD) Incidence Over Time Based on AP Exposure. A Results for the Entire Sample ( N = 795): no significant associations were observed between MCI + AD risk and long-term residential exposure to either O 3 (red; P = 0.57) or PM 2.5 (blue; P = 0.18). B Results from the “Matched Sample” sensitivity analyses of a subset of cognitively unimpaired participants matched to those with consensus MCI or AD diagnoses by age and sex ( N = 96): no significant associations were observed between long-term residential exposure to either O 3 (red; P = 0.91) or PM 2.5 (blue; P = 0.94) and MCI + AD risk
