Vitamin D in TB Prevention in School Age Children

ClinicalTrials.gov · COMPLETED, 2020

8,851 participants

Abstract

The goal of this clinical trial is to determine whether vitamin D supplementation reduces risk of acquiring latent tuberculosis infection (LTBI) in school age children in Mongolia. The investigators hypothesize that (1) vitamin D supplementation will reduce risk of acquisition of LTBI, (2) vitamin D supplementation will safely reduce risk of developing active TB and improve other secondary efficacy outcomes, and (3) children with the lowest vitamin D status at baseline will gain most from the intervention.

Conditions: Latent Tuberculosis.

Primary outcome: Acquisition of latent tuberculosis infection.

Enrollment: 8851 participants.

How strong is the evidence?

Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 8,851 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
