• 1 other identifier: 201412-878
• Study Type: observational
• Target: 100
• Locations: 0 countries
• Sites: N/A

Brief Summary

The purpose of this study is to determine the association between serum 25-hydroxyvitamin D and HbA1c levels in diabetic patients with chronic kidney disease. The investigators hypothesized that serum 25-hydroxyvitamin D levels were negatively correlated with HbA1c levels.

Conditions

Vitamin D Deficiency; Diabetes Mellitus

Outcome Measures

Primary Outcomes (2)

• 25-hydroxyvitamin D levels

  The unit of measure was nmol/L. The detection limit of the device was \<10 nmol/L. A mean value of 5 nmol/L were taken for results reported as \<10nmol/L.

  Within 2 weeks from enrolment

• HbA1c levels

  The unit of measure was percentage (using NGSP standarization).

  Within 2 weeks from enrolment
