[ 9 ] - Bone mineral density loss in postmenopausal onset rheumatoid arthritis is not greater than premenopausal onset disease

  Abstract   Background: Postmenopausal onset rheumatoid arthritis (post-RA) is expected to have greater bone mineral density (BMD) loss than premenopauasal onset (pre-RA) due to estrogen deficiency and aging. This study aimed to compare the BMD status of the two RA groups with age-matched non-RA controls.   Methods: The patients with RA on follow-up examination were stratified according to age...
