Abstract

fetched live from OpenAlex

PURPOSE OF REVIEW: Phosphate lowering toward the normal range is advocated and widely practiced in patients with end-stage renal disease receiving dialysis. This approach is guided by basic science data and large observational studies that have demonstrated a consistent association between hyperphosphatemia and adverse events, including cardiovascular morbidity and all-cause mortality. There has never been a clinical trial to assess the efficacy of phosphate lowering in maintenance dialysis recipients. RECENT FINDINGS: Despite several trials comparing the effect of different phosphate-binding agents on biochemical targets, no trial has evaluated whether targeting normophosphatemia using phosphate binders mediates better patient outcomes. Recent work has highlighted the feasibility of conducting a randomized trial comparing two strategies for phosphate control. We believe that this research question is optimally suited to a pragmatic trial design. SUMMARY: There is a pressing need for a well-designed randomized controlled trial to evaluate whether intensive phosphate lowering confers improved cardiovascular outcomes in patients receiving maintenance dialysis. We propose a broad framework for such a trial using the principles of pragmatic trial design. The ultimate objective of such a trial will be to provide patients and clinicians with reliable and broadly applicable information on whether reducing serum phosphate toward the normal range improves patient-important outcomes.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
