Abstract
BACKGROUND: We examined associations of C-reactive protein (CRP) levels with mortality in Japanese hemodialysis patients and trends in prevalence of CRP measurement at hemodialysis facilities internationally. To assess whether measurement of CRP may influence outcomes, we examined associations of facility prevalence of CRP measurement with mortality. METHODS: CRP measurements were from a cross-section of patients in the international Dialysis Outcomes and Practice Patterns Study (n = 610 facilities, 16,355 patients). Cox proportional hazards models assessed associations of mortality with CRP in Japan, and with a facility's frequency of measuring CRP internationally, (except in the USA and Canada). RESULTS: From 2002-2004, CRP was measured in 0-19% of patients in each country, except Japan (55%). From 2005-2007, CRP was measured in ≥ 50% of country patients except in Canada (15%) and the USA (2%). After multivariable adjustment, the hazard ratio (HR) of death was 1.6- to 2.4-fold higher (p < 0.05) for various categories of CRP levels >3 mg/l (vs. <1.0 mg/l). Cardiovascular mortality risk was lower in facilities measuring CRP for ≥ 50% of patients (HR = 0.72, p = 0.01) in multivariable-adjusted analyses. CONCLUSIONS: CRP is informative regarding mortality risk beyond that provided by other inflammatory and nutritional markers, with significantly higher risk seen at CRP >3 mg/l. Greater use of CRP may lead to improved patient care as suggested by the association of greater CRP measurement with lower cardiovascular mortality.

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
