Notes: For each contrast, degrees of freedom (df), t, P, and Cohen’s d values are presented. Cohen’s d was calculated with the following formula: 2t/√ (N − 2). 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).
Abbreviations: nsAL, alcoholic participants – currently not smoking; nsNA, nonalcoholic participants – currently not smoking; sAL, alcoholic participants (the comorbid group); sNA, nonalcoholic participants – current smokers.
