BMI, body mass index.

^aPoint values greater than zero confer increased the risk of 5-yr mortality. Point values less than zero confer the decreased risk of 5-yr mortality.

^bNonsignificant categories mean that the beta coefficients in the model were nonsignificant, and hence these categories are considered the same as the baseline category.

^cSmallest beta coefficient used to derive the scores.
