What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Total 25-hydroxyvitamin D concentration

    Total 25-hydroxyvitamin D concentration will be determined using liquid chromatography-tandem mass spectrometry in collected serum samples

    Measured: At baseline and weeks 4, 14 and 18

Secondary outcomes (2)
  1. Biomarkers of vitamin D metabolism

    Biomarkers of vitamin D metabolism, including parathyroid hormone and adjusted calcium will be quantified in collected serum samples by ELISA and using a clinical chemistry analyser

    Measured: At baseline and weeks 4, 14 and 18

  2. Dietary vitamin D intake

    Dietary vitamin D and calcium intake will be estimated using a validated food frequency questionnaire

    Measured: At week 18 only

Questions about this trial

What is this clinical trial studying?

A study testing 3000IU(75μg) vitamin D3 in people with Vitamin D Concentration and Vitamin D Status, run by University of Ulster at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 May 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Total 25-hydroxyvitamin D concentration (time frame: At baseline and weeks 4, 14 and 18). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 May 2016.
