Patients in the low cell viability group showed a trend towards experiencing more severe exacerbation in the previous year, were likely to walk approximately 34 m less in the 6-min walk test, and had higher levels of blood eosinophils than those in the high cell viability group; however, these differences failed to show statistical significance.
