Figure 2. Post Hoc Pain Scores Stratified by Study Group.

Median and worst daily pain scores are reported on a scale from 0 (best) to 10 (worst). Top and bottom of boxes indicate interquartile ranges; center lines indicate medians. Tukey error bars are shown, which extend to the farthest points that are not outliers. Outliers (black circles) were defined as values greater than 1.5 times the interquartile range.
