Notes: For each contrast, degrees of freedom (df), t, P, and Cohen’s d are presented. Cohen’s d was calculated with the following formula: 2t/√ (N – 2). For WCST: categories completed, Wilcoxon rank-sum Z is reported in place of t, and r = Z/√N in place of d.
*Significant interactions between smoking and alcoholism, where P<0.05. In purple: comorbid effects (sAL versus nsNA). In red: smoking effects (sAL versus nsAL or sNA versus nsNA). In blue: alcholism effects (sAL versus sNA or nsAL versus nsNA). In green: cross effects of smoking and alcoholism (sNA versus nsAL).
