aDrinks per day over the 3-month preceding detoxification. Drinks of each type of alcoholic beverage (wine, beer, and spirit) were standardized to units containing approximately 10 g of absolute alcohol (UIA).
bLaboratory norms.
CDT, carbohydrate-deficient transferrin; GGT, gamma-glutamyl-transferase; AST, aspartate aminotransferase; ALT, alanine aminotransferase; MCV, mean corpuscular volume; BDI-13, Beck Depression Inventory short form; HDRS, Hamilton Depression Rating Scale; HARS, Hamilton Anxiety Rating Scale; AUDIT, Alcohol Use Disorders Identification Test.
