Results of multiple linear regression analysis in patients with longstanding Crohn's disease (n=32), with absolute bone mineral density (BMD) and z scores of the lumbar spine as dependent, and vitamin D and “free” (uncarboxylated) osteocalcin as independent variables
| BMD of lumbar spine | Z score of lumbar spine | ||||||
|---|---|---|---|---|---|---|---|
| β | 95% CI | p Value | β | 95% CI | p Value | ||
| Vitamin D | 6.8E−4 | −0.005 to 0.007 | 0.885 | −1.2E−3 | −0.43 to 0.41 | 0.953 | |
| “Free” osteocalcin | −8.5E−3 | −0.17 to 0.000 | 0.050 | −6.8E−2 | −0.132 to −0.005 | 0.035 | |
β , weight factor; 95% CI, 95% confidence interval for β.
