Sensitivity analysis of relations between microvascular function and air pollution: two-pollutant models. Association of reactive hyperemia index (RHI) with a one interquartile range increase of ambient and personal air pollutants for exposures averaged across 1 day, 3 days, 5 days, and 7 days preceding each subject’s measurement (a) and the PM components in three different size-fractions for exposures averaged across 5 days preceding each subject’s RHI measurement (b). The sensitivity analysis is adjusting for ozone with the same averaging time, except for the ozone model, which adjusts for black carbon with the same averaging time. BC: black carbon; DTT: dithiothreitol; EC: elemental carbon; OA: Organic acids; OC: organic carbon; PAHs: polycyclic aromatic hydrocarbons;  PM particulate matter; ROS: reactive oxygen species; WS: water-soluble
