Effect modification of relations between microvascular function and air pollution by obesity status. Association of RHI score with one interquartile range increase of selected air pollutant exposures averaged across 5 days preceding each subject’s reactive hyperemia index (RHI) measurement: *p < 0.1, **p < 0.05, compared with no effect modification by obesity status. BC: black carbon; BMI: body mass index; DTT: dithiothreitol; EC: elemental carbon; OC: organic carbon; PAHs: polycyclic aromatic hydrocarbons; PM particulate matter; ROS: reactive oxygen species
