3. Fig 2
Cumulative morphine requirements (milligrams) in the first 24 postoperative h for the lidocaine and the placebo group. Data are shown as individual values and as mean (sd). There was no significant difference between the lidocaine group (closed circles, n = 35) and the placebo group (closed squares, n = 35) (P = 0.22).

Pain scores (as assessed with the numeric rating scale (NRS) for pain) in both groups during the first three postoperative days. No significant difference was found for the mean NRS between the two groups (main effect time: P < 0.0001; main effect group: P = 0.71; interaction effect: P = 0.59). m = min, h = h after arrival at the postanesthesia care unit, d = day.
