L. L. Zhang, Gong, J., and Liu, C. T., Vitamin D with asthma and COPD: not a false hope? A systematic review and meta-analysis, vol. 13, pp. 7607-7616, 2014.

Vitamin D deficiency and insufficiency are increasingly being recognized in the general population over the last few decades. However, a number of other disorders have now been linked to vitamin D deficiency and insufficiency, including asthma and COPD. The aim of this study was to evaluate the evidence on the effect of vitamin D on asthma and COPD. We searched electronic databases including SCI, EMBASE, Ovid, and PubMed. Reviewers working independently and in duplicate extracted study characteristics, quality, and the outcomes.
