Slope (g/kg per week) and associated y-intercept (g/kg) and standard error (SE) are shown for the 2 or 4 h exposure period by strain. Slopes sorted by 2 h exposure period. All slopes calculated from strain-averaged intake (4 h g/kg) or average weekly intake by strain (2 h g/kg). Bold italic slope values indicate significant (p < 0.05) effect of week on g/kg alcohol intake after linear regression. Intake is variable but generally increases over time for both the 2 and 4 h exposures in the BXD strains. However, slope at 2 h is not always identical to slope at 4 h and both traits are modestly correlated (r = 0.41). Parental strains are highlighted.
