Data are % or odds ratios (95% CI) based on logistic regression for the individual paired comparisons between treatment groups. All data are based on the 20 multiple imputation datasets. HCD=higher cigarette dependence at baseline (Fagerström test for nicotine dependence ≥2).
*
Odds ratios are statistically significant with α=0·0167 for eTARGET versus ASSESS, α=0·025 for GENERIC versus ASSESS, and α=0·05 for GENERIC versus eTARGET.
