Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether cholecalciferol supplementation decrease the blood concentrations of hepcidin-25 in hemodialysis patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

There are 4 arms in this study: (1) Thrice-weekly cholecalciferol supplementation (3,000 IU), (2) Monthly cholecalciferol supplementation (equivalent to 9,000/week), (3) Thrice-weekly placebo, and (4) Monthly placebo. The primary analyses will be done regarding 2 cholecalciferol groups and 2 placebo groups as one group each, and we will evaluate the effect of cholecalciferol regardless of the supplementation regimen. As the secondary analyses, we will examine if there is any difference between thrice-weekly and once-monthly supplementation regimen.
