ALB and diabetes mellitus: Regarding FN BMD, six variables were significantly associated with OP in the diabetes group: menopause duration (B = 0.117, p < 0.001), age (B = 0.126, p < 0.001), and albumin levels (B = 0.109, p = 0.016) were positively correlated, whereas estrogen levels (B = −0.098, p = 0.003), BMI (B = −0.100, p = 0.011), and total calcium levels (B = −2.86, p = 0.016) showed negative associations.
