Changes in glucose tolerance after air or ozone exposure in SHAM, DEMED, or ADREX rats. GTT was performed only after the first day of exposure in the 2-D group (A). The 0 min time point shows fasting glucose levels in each group postexposure. Panel B shows the graph for the AUC for the GTT data. Values indicate mean ± SEM (n = 4–6/group). *Indicates ozone effect when compared with matching air group (P ≤ .05). AUC, area under the curve.
