Figure 5
Length of postoperative intensive care unit stay in the dexamethasone and placebo groups. Box-plot of postoperative intensive care unit length of stay is shown. Whiskers represent the last datum within 1.5 times the interquartile range. Median (interquartile range) lengths of stay were 21.9 (4.3) hours in the dexamethasone group and 22.7 (24.5) hours in the placebo group (P <0.001) (log-rank test). Note the difference between the median and mean lengths of stay (Table 3).
