Individualized prediction of mortality using multiple inflammatory markers in patients on dialysis.
This study aimed to evaluate whether the combination of inflammatory markers could provide predictive powers for mortality in individual patients on dialysis and develop a predictive model for mortality according to dialysis modality. Data for inflammatory markers were obtained at the time of enroll...
