  • Data are presented so that coefficients represent the change in dialysate-to-plasma creatinine ratio. A total of 499 and 307 patients were in the final models for incident and prevalent patients, respectively. Cytokine coefficients are per log10 changes in concentration. CI, confidence interval.

  • a P=0.01–0.05.
