Notes: 1) Values are means ± S.E.M. Significant P values after correction for multiple testing are given in bold. “Years of lifetime drinking” was calculated by subtracting the age at which the subject began experiencing symptoms of alcohol dependence from their age at study enrollment.

2) The adjusted P value at the 0.05 significance level is 0.010.
