  1. Multiple regression analyses of bone mineral density by digital x-ray radiogrammetry and by dual energy x-ray absorptiometry and of joint destruction assessed by Larsen score in postmenopausal women with rheumatoid arthritis.
  2. Beta values are unstandardized coefficients. The R2 is the total variance explained in the model. SE = standard error
  3. ICTP = C-terminal telopeptide of type I collagen
