  1. Values are presented as mean ± standard error. P value indicates the significance of the difference in each parameter value between patients and control subjects. aOne patient with rheumatoid arthritis was removed from the bone mineral density analysis because of her diagnosis of osteosclerosis. NS, not significant (p > 0.10).
