Median cumulative consumption of oxycodone over 48 h postoperatively. 6 h: p = < 0.001; 12 h: p = < 0.001; 24 h: p = 0.03; 48 h: p = 0.03. The Bonferroni-adjusted p-value for the 48-h time point was 0.1. The line in the middle of the box represents the median. The lower and the upper edges of the box are the 1st and 3rd quartile, respectively. If an observation is beyond 1.5 times interquartile range it is considered as an outlier and marked by a dot. Whiskers are the lowest and highest values that are not outliers.
