OR, odds ratio; CI, confidence interval; BMI, body mass index; LS, lumbar spine; BMD, bone mineral density; FN, femur neck.

^*The association in participants aged <50 years could not be analyzed due to a lack of patients with diminished renal function (men, n=7; women, n=2), ^†Statistically significant difference.
