Kaplan-Meier curves of fracture-free survival in early RA, according to BMD at inclusion. Illustrates Kaplan-Meier curves of cumulative fracture-free survival in 604 patients with early RA, according to BMD at inclusion. Normal BMD was defined as the lowest T-score more than − 1.0 SD, osteopenia as a T-score − 1.0 to -2.5 SD, and osteoporosis if a T-score of -2.5 SD or less. Fracture occurrence by BMD of lumbar spine: fractures occurred in 17 out of 239 patients with BMD within the normal range, in 28 out of 212 patients with osteopenia, and in 52 out of 151 patients with osteoporosis. Fracture occurrence by BMD of hip: fractures occurred in 13 out of 202 patients with BMD within the normal range, in 42 out of 260 patients with osteopenia, and in 22 out of 140 patients with osteoporosis
