I thought this was an interesting review of this study. It's about a 2:40 min video to watch where he describes what a pragmatic study is and then goes over the results.
I thought it did highlight that more research, and different types of research, need to be done on probiotics and how they can effect asthma (or other diseases)
Do you take probiotics? Have you noticed any (anecdotal) changes to your asthma health? I sometimes take packaged probiotics and sometimes rely on live cultures/fermented foods. I notice that I feel better overall, but have not noticed anything particular with my asthma and allergies.
Pragmatic trial may not be enough to determine the efficacy
The hope that probiotics would improve outcomes in patients with asthma may have been dealt a knock-down, but not a knock-out blow, as MedPage Today clinical reviewer F. Perry Wilson explains in this 150 Second Analysis.
