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 2-year mortality in patients with achievement of P target values and Ca is compared between calcimimetics users and non-users. In addition, chi-square tests is performed to assess the 1-year and 2-year mortality on patients whose P, Ca, and PTH are outside the target range.

Other related information
In this retrospective 2-year observational study, we compare the 2-year mortality between calcimimetic users and non-users whose either P or Ca level was within the target range. 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 range were annually censored by checking the use of calcimimetics, dialysis method (HD, pre-dilution OHDF, and post-dilution OHDF), albumin leakage (<3 g/session and >3 g/session), and laboratory values for P or Ca. 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 between calcimimetic users and non-users whose P, Ca, and PTH levels were below and above the target range. 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.
