For the article by Segawa et al. in the December 1998 issue of Anesthesiology (1998; 89(6):1407-13), the authors would like to make the following correction:Figure 1and Figure 2were duplicates. The correct Figure 1appears here (right).

Figure 1. Plasma norepinephrine (upper) and epinephrine (lower) concentrations during isoflurane anesthesia. Box-and-whisker plots represent the 10th, 25th, 50th (median), 75th, and 90th percentile of catecholamine concentrations at each sampling point. * Significant difference versus the values at -1 min (P < 0.05).
