Abstract

fetched live from OpenAlex

The role of transplant nephrectomy after transplant failure is uncertain. We report the use and consequences of transplant nephrectomy among 19 107 transplant failure patients between 1995 and 2003 in the United States. Among 3707 patients with early transplant failure (graft survival <12 m), nephrectomy was performed in 56%, and was associated with an increased risk of death (HR 1.13, 95% CI 1.01-1.26). In contrast, among 15,400 patients with late transplant failure (graft survival > or =12 m), nephrectomy was performed in 27%, and was associated with a decreased risk of death (HR 0.89, 95% CI 0.83-0.95). In early transplant failure patients, nephrectomy was associated with a lower risk of repeat transplant failure (HR 0.72, 95% CI 0.56-0.94), while among late transplant failure patients; nephrectomy was associated with a higher risk of repeat transplant failure (HR 1.20, 95% CI 1.02-1.41). Definitive conclusions are not possible from this observational study. The role of nephrectomy in the management of dialysis treated transplant failure patients, and the implications of nephrectomy for repeat transplantation should be further studied in prospective studies.

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.
