Cohort study
14. Follow-up of patients

15. Data analysis plan
Please provide a brief summary of the analysis method
Summary statistics will be produced for all baseline variables. The baseline variables for the two cohorts will be compared using the following tests:
• Variables measured on the interval/ratio scale:
− t-test (normal distribution)
− Mann-Whitney U test (skewed data)
• Categorical variables:
− Chi-square test
Results will be reported as:
• Variables measured on the interval/ratio scale:
− Sample size (n) and percentage non-missing
− Median and inter-quartile range (25th and 75th percentiles)
• Categorical variables:
− Sample size (n)
− Count and percentage by category (distribution
If sufficient numbers are achieved, patients will be matched on baseline variables to assess outcomes between the control (remain on DPI) against comparator (MDI)
