  2. aAdjusted for all variables in this table, plus age as a continuous variable. Alcohol abuse includes only individuals who did not also meet the criteria for alcohol dependence (N = 80). Due to power constraints, analyses based on ethnicity have been collapsed into Sinhala and non-Sinhala categories
