There were significant differences among the groups. b TSH levels in the three groups. There were significant differences among the groups. c Age at menopause in the three groups. There were significant differences among the groups. d Comparison of the relative risk ratios of TSH categorised by BMD rate of change. Values were adjusted for age and body weight. Error bars represent 95% confidence interval for the mean changes. Mild, mild bone density loss group; moderate, moderate bone density loss group; severe, severe bone density loss group; BMD, bone mineral density; TSH, thyroid-stimulating hormone. *p < 0.05
