Fig. 5From: Associations between microvascular function and short-term exposure to traffic-related air pollution and particulate matter oxidative potentialEffect 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 speciesBack to article page
