Distribution of categorical responses on the PGA at 24 h. The percentages of patients who reported PGA ratings of success (‘excellent’ or ‘good’ responses) in the fentanyl ITS and morphine PCIA groups were 86.2 and 87.5%, respectively (95% CI, −6.5 to 3.9%).

Mean pain intensity scores over time. Pain intensity scores were similar between groups at each measured time point throughout the study. In addition, the 95% CI for the difference in the mean last pain intensity scores indicated non-inferiority of the fentanyl ITS compared with morphine PCIA after the first 24 h (95% CI, −0.18 to 0.38) and at the last patient assessment (95% CI, −0.38 to 0.18). Error bars represent standard deviations.
