Abstract
Aim: Palbociclib (PAL), ribociclib (RIB) and abemaciclib (ABM), in combination with fulvestrant (FUL), are approved for the treatment of hormone receptor-positive, HER2-negative advanced breast cancer. This study aims to determine relative efficacy of PAL+FUL versus RIB+FUL and ABM+FUL using matching-adjusted indirect treatment comparisons. Patients & methods: Anchored matching-adjusted indirect treatment comparisons were conducted using individual patient data from PALOMA-3 and published summary-level data from MONARCH 2 and MONALEESA-3. The primary outcome was overall survival (OS). Results: OS was similar for PAL+FUL versus ABM+FUL (hazard ratio: 0.87; 95% CI: 0.54–1.40) and RIB+FUL (hazard ratio: 0.89; 95% CI: 0.48–1.63). Conclusion: Adjusting for cross-trial differences suggests similar OS between treatments, underscoring the importance of accounting for these differences when indirectly comparing treatments.

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
