Figure 3

Mean scores on the Questionnaire of Smoking Urges (QSU) scale. The figure shows the changes in the mean scores on the QSU over the 3-week study period in the group receiving placebo (placebo group), those receiving atomoxetine who completed the study (atomoxetine group), and those who received atomoxetine but dropped out during the study (last observation carried forward (LOCF) atomoxetine group). A two-sample t test demonstrated statistically significant difference (P < 0.05) between the atomoxetine group and placebo groups at 2 weeks (*), but this just failed to reach statistical significance at 3 weeks.
