In the published article, there was an error in Figure 1 as published. The Figures 1B, C were incorrect and appeared inverted in the figure caption.
FIGURE 1
FIGURE 1. Concentrations of tramadol (A), N-demethyltramadol (B), and O-demethyltramadol (C) in the first 24 postoperative hours. Concentrations were measured 1, 2, 4 h after the first dose of 100 mg tramadol iv, and just before the second (time point 6 h), third (time point 12 h), and fifth (time point 24 h) doses of tramadol. PM, poor metabolizer; IM, intermediate metabolizer; EM, extensive metabolizer; UM, ultrafast metabolizers; Dot, tramadol 100 mg IV injections; * statistically significant differences (Mann-Whitney U test) between PM and EM/IM (B), and EM and IM/PM (C).
The corrected Figure 1 and its caption appear below.
