Objectives

Narrative objectives1

A propensity score matching model and adjusted Cox regression analysis is used in a retrospective 2-year observational study. The effects of mortality in patients within target Hb range grouping by users and non-users with ESAs and/or calcimimetics . In addition, chi-square tests is performed to assess the 1-year and 2-year mortality on patients whose Hb values are within and outside the target range grouping by users and non-users with ESAs and/or calcimimetics.

In this retrospective 2-year observational study, we compare the 2-year mortality in patients within target Hb range grouping by users and non-users with ESAs and/or calcimimetics. 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 or cases outside the target Hb range were annually censored by checking the use of ESAs, HIF-PH inhibitors, calcimimetics, and dialysis method (HD, pre-dilution OHDF, and post-dilution OHDF). We then performed Cox proportional hazards analysis with adjustments. In addition, we perform chi-square tests to evaluate the 1-year and 2-year mortality in patients within and outside the target Hb range grouping by users and non-users with ESAs and/or calcimimetics. The 1-year mortality and 2-year mortality are expressed as the ratio of 1-year and 2-year deaths to the number of patients in each group.
