Comparison of survival between short‐daily hemodialysis and conventional hemodialysis using the standardized mortality ratio
Bibliographic record
Abstract
More frequent hemodialysis (5 or more times weekly, both short during the day and long overnight) has been shown to improve patient well-being, reduce symptoms during and between treatments, and have beneficial effects on clinical outcomes. Because of the relatively small patient sample sizes, there are little or no data on mortality from any single study at this time. This study compares survival in 117 U.S. patients treated by short-daily hemodialysis in 2003 and 2004, with patients reported in the 2003 data from the United States Renal Data System (USRDS). Expected mortality was calculated from the USRDS and compared with observed actual mortality. The standardized mortality ratio (SMR) was used to adjust for differences in patient age, sex, race, and cause of renal failure. The SMR for the short-daily hemodialysis patients was 0.39, statistically significantly better (p < 0.005) than data from the overall U.S. population of hemodialysis patients and indicating that daily hemodialysis patients had a 61% better survival. Patients treated by short-daily hemodialysis have a better survival rate than comparable populations treated by conventional hemodialysis.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
