Study questions
What is the purpose of the study?
The purpose of the study is to analyze the effect produced by vitamin D3 on the treatment of asthma in people that have both a lower level of vitamin D and symptomatic asthma.
How many participants are in the experimental group?
1523 participants participated in the study. 408 participants were randomized. There were two groups: the vitamin D3 group or the experimental group and the placebo group or control group. In the vitamin D3 group, there were 201 participants.
How many participants are in the control group?
In the control group, there were 207 participants.
What variable(s) is/are being tested in the control group?
The variable that was tested was narrowed to how the supplementation of vitamin D influenced the clinical efficacy of corticosteroids that were inhaled in patients that suffer from asthma caused by functions of lungs, exacerbations, and a particular dose of corticosteroids that are required to control asthma during different periods of time. Describe the nutrition assessment method(s) used in the study. Specific lab tests were used as the nutrition assessment methods. This nutrition assessment method was used to measure individual nutrients in the fluids of the body (vitamin D).
What were the results of the study?
Based on the results of the study, the completion rate was very similar in the placebo group (95% CI, 83%-92%) and in the vitamin D3 group (95% CI, 85% - 93%). Interquartile range was about 27.6-28.7 weeks.
What contribution does this research make to nutrition knowledge?
The study was very educational and helpful at the same time. It informed readers about possible effects of vitamin D on the treatment failures of asthma. This information is vitally important for medical specialists. Taking this information into consideration, they can take measures to reduce possible negative effects of vitamin D on the treatment failures of asthma in people who suffer from symptomatic asthma and have lower levels of vitamin D.
What/who are the major funders of the research?
Mario Castro, MD, MPH, Tonya S. King, PhD., Susan J. Kunselman, MA, Michael D. Cabana, MD, MPH, Loren Denlinger, MD, PhD, and others are the major funders of the research.
How many references are cited?
29 references are cited in the study.
What are some of the strengths and/or weaknesses of the study?
The study has a lot of strengths and weaknesses. The authors of the article used effective sources to support their research. They provided sufficient definitions, figures, graphs, and tables …
