Regression analysis of g/kg ethanol (10E) intake and μg/dL corticosterone (CORT) levels following select stressors in Cohort 1. There was no relationship between CORT levels in male and female mice following restraint or tail suspension stress and 10E intake on the day of (A and C, respectively) or the day after (B and D, respectively) administration of the stressor. However, in female mice, there was a significant positive linear relationship between CORT levels and ethanol intake on the first day post restraint stress (B; r2=0.42, p<0.05), indicating that 42% of the variance in 10E intake on the day after restraint stress could be explained by CORT levels immediately after restraint. Although levels of CORT were not related to 10E intake on the day of predator odor stress (E), there was a significant positive relationship (p<0.05) between CORT levels and ethanol intake on the day after exposure to the predator odor (F) in male and female mice. The r2 value indicates that 26% of the variance in 10E intake on the day after predator odor stress could be explained by CORT levels immediately after predator odor exposure.
