Outcomes

Primary Outcome Measures

Differences in changes in PTH levels from baseline to 6 months of intervention

Secondary Outcome Measures

Differences in changes in PTH levels from baseline to intervention at 1months、2months、3months、4months、5months
Proportion of 25(OH)D >30ng/ml at 3 months of intervention
Trends in changes in 25(OH)D levels from baseline to intervention at 1months、2months、3months、4months、5months、6months
Incidence of cardiovascular events after 6 months of intervention
Change in prevalence of vascular calcification at 6 months of intervention
We used cardiac ultrasound and lateral abdominal views to look for vascular calcification
Change in Montreal Cognitive Assessment Scale scores at 6 months of intervention
A total score of 30 on this scale, with a score of ≥26 indicating normal; a score of <26 indicates the presence of cognitive impairment: 18-26 for mild cognitive impairment, 10-17 for moderate cognitive impairment and <10 for severe cognitive impairment
Trends in blood calcium levels at 1 month, 2 months, 3 months, 4 months, 5 months and 6 months of intervention
Trends in blood phosphorus levels at 1 month, 2 months, 3 months, 4 months, 5 months and 6 months of intervention
Trends in FGF23 levels at 3 and 6 months of intervention
Trends in Osteocalcin(OC) levels at 3 and 6 months of intervention
Trends in Precollagen type I amino-terminal peptide(PINP) levels at 3 and 6 months of intervention
Trends in β specific collagen degradation products(β-CTX) levels at 3 and 6 months of intervention
Trends in ALP levels at 3 and 6 months of intervention
Incidence of fractures at 6 months of intervention
Ask if the patient had a fracture during the intervention, the site of the fracture and the type of fracture
Incidence of falls at 6 months of intervention
Ask if the patient has fallen during the intervention, the number of falls and the reasons for them

5. Study Description

Brief Summary
Study content: This is a multicentre, double-blind, randomised controlled study to determine the optimal dose and duration of treatment for the correction of vitamin D insufficiency or deficiency in patients with CKD5d; to investigate whether vitamin D supplementation delays the increase in PTH levels in this group of patients; and to investigate the effects on changes in CKD-MBD-related markers, cardiovascular complications, cognitive function in this group of patients. 2. Study procedure: Based on the inclusion and exclusion of the patients, the study was conducted in accordance with the following criteria Study procedure: Eligible subjects were screened according to inclusion and exclusion criteria and randomly divided into three groups: high-dose vitamin D group, low-dose vitamin D group and control group. Baseline data were collected before the intervention and each group was given different doses of regular vitamin D2 softgels or placebo and followed up. 25(OH)D, PTH, blood Ca, and blood P levels were measured every month; bone metabolism markers, FGF23, and blood counts, liver function, kidney function, lipids, and blood glucose were measured every 3 months; the prevalence of vascular calcification, the incidence of cardiovascular events, and changes in cognitive function scale scores were assessed 6 months after the intervention.

Intervention Description
placebo was filled with excipients (aniseed ether, refined vegetable oil), and the shape and size were the same as vitamin D2 soft capsule.the control group was given placebo, 5 placebo capsules twice weekly for 6 months of the intervention. The medication was dispensed by a designated person (not the investigator) in advance and independently according to the patient's medication number (only the drug number was provided on the outer packaging).
