Table 1.

Daily oxycodone consumption

POD	Placebo Block & 50 h Placebo Infusion	Levobupivacaine Block & 50 h Placebo Infusion	Levobupivacaine Block & 50 h Levobupivacaine Infusion
1	42^* (37-47)	33 (29-37)	30 (26-34)
2	27 (23-31)	28 (24-32)	25 (22-28)

Values are reported mean (95% confidence interval) and include both immediate- and sustained-release oxycodone [the source document by Williams and colleagues did not separate immediate-release oxycodone from sustained-release oxycodone use, and therefore these two different formulations cannot be presented individually in this table]

POD: Postoperative Day

There were no statistically significant differences among the groups other than for postoperative day 1

P<0.001 for the Placebo/Placebo group compared with the other two treatment groups Adapted from Table 2, Williams and colleagues¹
