PTH and diabetes mellitus: Model 3 showed comparable correlations between APOA1 and lumbar BMD (β = 0.07, 95% CI = 0.02 to 0.11, p = 0.0045), and APOA1 and β-CTX (β = −0.19, 95% CI = −0.29 to −0.09, p = 0.0003), after controlling for age, BMI, triglycerides, ALT, UA, diabetes, hypertension, monocyte, hemoglobin, platelet, and PTH.
