Study design details

• Main study objective:
  Compare for large particle vs small particle ICS:Diagnosis of pneumonia First diagnosis of type 2 diabetes and/or prescription for anti-diabetic medication Progression of ongoing type 2 diabetes treatment to insulinChange in anti-diabetic medication (e.g. type or dose prescribed) Change in HbA1c valueChange in BMI
• Outcomes:
  Co-primary outcomes:(i) First diagnosis of diabetes and/or prescription for anti-diabetic medication (ii) Progression of ongoing diabetes treatment to insulin(iii) Change in HbA1c value(iv) Change in anti-diabetic medication (e.g. type or dose prescribed) (v) Change in BMI (vi) Diagnosis of pneumonia (vii) Exacerbation of obstructive lung disease
• Data analysis plan:
  Treatment arms will be compared using (conditional) logistic regression, Poisson regression and Cox regression.
