Thanks @cwal. I am familiar with this study. It is certainly interesting, but by its own words is not conclusive, instead stressing the need for clinical trials on the use of hypertonic saline with NTM disease. I believe there is one, maybe two, clinal trials currently underway on the subject. But I am not aware of any clinical trials on the subject with published results. If anyone has different information I would love to know about it. Thanks.
