BMD measurement at hip and spine. Normal BMD = T score ≥ −1.0, osteopenia = −2.5 < T score < −1.0, and osteoporosis = T score ≤ −2.5. Values are n (%).
↵* Calculated in 46 patients because 3 patients had a bilateral hip replacement.
↵† Change of BMDhip, p = 0.014.
↵‡ Change of BMDspine, p < 0.001. BMD: bone mineral density; ETN: etanercept; total BMD: BMD hip and spine.
