Effect of diesel exhaust (DE) exposure on brachial artery caliber: postexposure − preexposure session difference in adjusted mean brachial artery diameter (BAd) comparing DE exposure to filtered air exposure. (A) Antioxidant (AO)–DE effect with mixed models demonstrating the overall DE effect, the impact of the placebo (DE/PL), and the impact of the antioxidant regimen (DE/vitamin C + N-acetylcysteine). (B) Gene–pollutant effect with mixed models demonstrating the overall DE effect and the DE effect in preselected genotypes of AGTR1, GSTM1, and TRPV. wt = wild type.
