The new body mass index formula; not validated as a predictor of outcome in a large cohort study of patients undergoing general surgery

This study showed no difference in prediction of outcome after general surgery when comparing the current BMI formula to the new BMI formula. Thus, despite the fact that the new mathematical proposition seemed more logical and interesting, both calculations can be used in clinical practice. Moreover, our results do not support a change from the conventional BMI formula, currently used and accepted worldwide.
