In this retrospective observational study, we compare the 2-year mortality on users and non-users of calcimimetics in patients withour protein-energy wasying and inflammation, and patients with protein-energy wasting and/or inflammation. Using a propensity score matching model and Kaplan-Meier method, we daily censored deaths and transfers to other hospitals. In addition, transfers to other group is annually censored by checking the use of calcimimetics, dialysis method (HD, predilution OHDF, and postdilution OHDF), albumin leakage (below 3 g/session and over 3 g/session), and protein-enegy wasting and/or inflammation. We then performed Cox proportional hazards analysis with adjustments for some covariates that remained significantly different between the groups. In addition, we perform the stratified analysis by median age to compare 2-year mortality rate between calcimimetic users and non-users in patients without protein-energy wasting and inflammation, and patients with protein-energy wasting and/or inflammation. Furthermore, we compare cumulative 2-year survival by the Kaplan-Meier method among groups.
