  1. Pearson correlation coefficients for linear regression between BRS slope and various physiologic and exposure endpoints in MetS and ND-fed rats over the course of the entire exposure period, including both filtered air- and P + SOA-exposed animals. Pearson partial correlation was conducted for air pollutant concentrations. *, **, and *** indicate P < 0.05, 0.01, and 0.001, respectively. Dash alone indicates parameter was not analyzed
