Table 3. Relationships of duration of heavy drinking (DHD, years) to cerebellar volume for AL men and women.
The 95% confidence interval (CI) of the slope (B) for volumes (as a proportion of estimated total intracranial volume, expressed as a percentage of the overall means) and partial r2 as a function of DHD are presented for all alcoholics combined, as well as AL men and women separately. Partial r2 was calculated with the formula: SSterm/(SSterm + SSerror). Age was included as a covariate for all analyses. Effects significant at p < 0.05 are in bold. *DHD by gender interaction (p < 0.05).
