  1. IMST, inspiratory muscle strength training; n, number of subjects taking that category of drug, followed by the percent of the group taking that drug category. P values for proportions were calculated with chi square, corrected with Yate's correction for cells with five or less subjects. Mean drug days = mean number (± standard deviation) of drug days for the subjects taking that category of drugs. For example, if a patient took two different antibiotics for four days, that patient would have accumulated eight drug days for the antibiotic category. Drug days were tested with unpaired T tests.
