↵a Compared with person without this characteristic. NS = not significant. Hazard ratios were adjusted for all other terms in the table and models accounted for age as underlying time function and also included fractional polynomial terms for body mass index (BMI). For females, the terms were BMI−2, ln(BMI). For males the terms were BMI−1, BMI−1ln(BMI).
