Abstract
OBJECTIVE: In a 3-year randomized, double-blind, osteoporosis treatment study (N = 7,492), bazedoxifene 20 mg and bazedoxifene 40 mg significantly (P < 0.05) reduced the risk of new vertebral fractures by 42% and 37%, respectively, compared with placebo in postmenopausal women with osteoporosis. This study evaluated the long-term (7-y) efficacy and safety of bazedoxifene in generally healthy postmenopausal women with osteoporosis. METHODS: This was a second 2-year extension of the 3-year multicenter outpatient core study. During extension I (years 4-5), women receiving bazedoxifene 40 mg transitioned to bazedoxifene 20 mg. In extension II (years 6-7; N = 1,530), all bazedoxifene-treated women continued bazedoxifene 20 mg. Main outcome measures included year 7 endpoints: incidences of new vertebral and nonvertebral fractures, bone mineral density changes, and safety assessments. RESULTS: At 7 years, the cumulative incidences of new vertebral fractures were significantly lower in the bazedoxifene (6.4%) and bazedoxifene 20 mg (7.6%) groups than in the placebo group (9.9%); the relative risk reductions were 36.5% and 30.4%, respectively (both P < 0.001). Bazedoxifene had no effect on the overall incidence of nonvertebral fractures (bazedoxifene, 11.2%; bazedoxifene 20 mg, 12.0%; placebo, 10.8%). The mean changes from baseline in lumbar spine bone mineral density were 2.95%, 2.73%, and 2.19%, respectively. Seven-year decreases in total hip bone mineral density were significantly smaller in the bazedoxifene (-1.15%) and bazedoxifene 20 mg (-1.19%) groups than in the placebo group (-2.53%; P ≤ 0.002). Bazedoxifene showed a favorable safety/tolerability profile across 7 years, with similar adverse events, serious adverse events, and study discontinuations in all groups. CONCLUSIONS: Efficacy and safety of bazedoxifene are sustained across 7 years in postmenopausal women with osteoporosis.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
