Soohoo M, Molnar MZ, Ujszaszi A, et al. - Researchers used adjusted Cox models to determine the link of baseline and time-varying red blood cell distribution width (RDW) with the risk of mortality and time to first hospitalization in 14,323 incident peritoneal dialysis (PD) patients in the USA. They used an adjusted negative-binomial regression model to assess the link of baseline RDW and hospitalization rate. The study sample included patients 56 ± 16 years of age, comprising 43% females, 23% African Americans and 62% diabetics. The mean RDW was 15.3 ± 1.6%. Findings revealed the link of higher RDW with a higher risk of mortality and hospitalizations among incident PD patients.
