An ANOVA model was used to examine the characteristics of the three DI groups for age, FHD, craving (PACS), and AUDIT (Table 1A) by using DI group as a predictor variable. Tukey‐corrected pairwise comparisons were used to identify how the groups differed. A chi‐square test was used to test whether gender and nicotine use was associated with the DI groups.
