p.3 left column bottom paragraph:"The overall mean BSA for the patient population was 1.79 m^2 (95% CI 1.78, 1.80). For both sexes, the BSA distribution was approximately normal as shown in figure 2. The mean BSA for men was 1.91 m^2 (1.90, 1.91) compared to 1.71 m^2 (1.70, 1.72) for women, with a median of 1.90 and 1.70 respectively. Previous studies have employed the mean in preference to the median, a convention [investigators] have continued as the distribution approximated normal, and the mean better incorporates outliers which may have significant effects on costing." |
