Figure 1 shows the BrAC curves at initial and re-examination testing for light and heavy drinkers. BrAC peak levels at 60 minutes were slightly higher at initial testing in the HD vs. LD (94 vs. 85 mg/dl, respectively, p<.001) but at re-examination there were no differences [89 vs. 85 mg/dl, p=.126]. All analyses controlled for peak BrAC levels at each testing phase.
