Assessment

Primary outcomes

The change in coronary artery calcification score (CACS) and a proportion of patients with more than 15 percent annualized increases in CACS

[Sample size analysis and Interim Analysis]
We estimated that a sample size of 222 patients (111 in each group) would provide a power of 90% at an overall two-sided alpha error level of 0.05 to detect a 30% relative reduction in the percent change in CAC scores in the magnesium oxide group compared to the control group, given that an annual percent change in CAC score among pre-dialysis diabetic CKD patients was 14% according to a previous study. Assuming a dropout rate of approximately 10%, we planned to enroll a total of 250 patients.
An interim analysis for efficacy was to be performed after a half of the planned number of patients (i.e., 125 patients) reached the end of the study, with use of the Lan-DeMets alpha-spending-function approach (Pocock type).
According to a result of the interim analysis, an independent data monitoring committee determines whether the study should be continued or prematurely terminated.
