aDescriptive statistics for BMI for females is limited to the 707 women who were not pregnant during the 2005 blood draw, and the T-test evaluating male-female differences in BMI was also calculated among this subset. Please see methods for discussion of how non-pregnant BMIs used in regression models were calculated.
