Results of multiadjusted linear mixed models on associations between air pollution in $particulate matter begin subscript 2.5 end subscript$ and ${NO}_{x}$ (5-y mean prior baseline assessment, quartiles) and change (score/year) in odor identification in SNAC-K participants without anosmia at baseline ( $lowercase italic n equals 2280$ ) and in those without a history cerebrovascular disease at baseline ( $lowercase italic n equals 2362$ ).
