Fig. 2From: Postoperative analgesia for upper gastrointestinal surgery: a retrospective cohort analysisProbability of poor rest (a) or dynamic (b) pain control if one were to have a different analgesic technique. The plot shows the posterior predictive distribution of the probability of poor pain control of the original analgesic technique, the posterior predictive distribution of the probability of poor pain control if one were to have a different analgesic technique, and the distribution of the differences in the probability of poor pain control (grey). The black error bars reflect the 95% credible intervalsBack to article page
