CRP and hyperphosphatemia: A fourth “Combined model” that included all statistically significant factors in the three separate models, showed that suboptimal DI, physical PD contraindication, HD contraindication, Other contraindications, hyperphosphatemia, inflammation (elevated CRP), edema and cerebral symptoms were associated with increased risk of death within one year after DI, independent of age, sex, renal diagnosis and comorbidity (Fig. 4), whereas eGFR at DI or rate of loss of eGFR prior to DI was not related to mortality.
