  1. For studies requiring patients to be treated with ICS or ICS/LABA at baseline; full covariate model
  2. *Other relevant ICS/LABA: FP/SAL 250/50 mcg and 500/50 mcg; BUD/FORM 320/9 mcg and 640/18 mcg
  3. a) change from baseline in morning PEF. b) change from baseline in FEV1. c) annual rate of moderate/severe exacerbations. d) AQLQ Total score
  4. Only study length was included as a covariate in analysis of moderate/severe exacerbations data
  5. Note: All stated doses are mcg
  6. AQLQ Asthma quality of life questionnaire, BUD Budesonide, CrI Credible interval, FORM Formoterol, FEV 1 Forced expiratory volume in 1 s, FF Fluticasone furoate, FP Fluticasone propionate, PEF Peak expiratory flow, SAL Salmeterol, VI Vilanterol
