Mean (SD) of symptom score at baseline (i.e., 30 minutes prior to stressor) on factors 1 and 2 of the Questionnaire of Smoking Urges (QSU) and Least Squared Mean (95% CI) of difference in response between control and active conditions. Stress response was calculated as change in symptom severity (post-stress minus pre-stress). Stress response difference between control and active was calculated by subtracting the stress response for the experimental condition from stress response for its control condition. Post stress severity difference was calculated by subtracting post-stress severity score in experimental condition (controlled for baseline) from severity score in its control condition (controlled for baseline). Asterisk (*) indicates difference in score between experimental and control at p<0.05.
