Significant predictors of participants being in the “late relapser” category.

Predictor	Odds ratio (95% upper confidence bound)	One-sided p-value
SIT	0.958 (1.000)	0.0488
SIT – SCN	0.899 (0.988)	0.0322
Fagerström	0.422 (0.841)	0.0198

Odds ratios, and 95% upper confidence bounds, and one-sided p-values for measures observed during the participant-intake visit. An odds ratio < 1 indicates the proportional decrease in the probability of being a “late relapser” when the predictor measure increases by 1 unit. A late relapser is defined as a participant whose grand mean of incentive-schedule relapse times was greater than or equal to the cross-participant median of such averages. SIT = Stroop interference task score; SCN = Stroop color-naming task score. Fagerström = score from the Fagerström Test for Nicotine Dependence. See the text for how the predictor scores are determined.
