Each variable in the Predictor column represents an odds ratio generated in a model that included baseline nicotine dependence as a covariate and each of the listed predictors (Mean Symptoms, Acute Elevation, and Lagged Acute Elevation). There was not a statistically significant relationship of nicotine dependence to smoking occasions in any of the models presented. PTSD = posttraumatic stress disorder. OR = Odds Ratio. CI = Confidence Interval. Mean Symptoms = mean of all ecological momentary assessment symptom ratings by the participant across the pre-quit phase. Acute Elevation = magnitude of elevation of a given assessment above that participant’s individual mean symptom level. Lagged Acute Elevation = Acute elevation from the assessment before the one being analyzed.
