Mean FEV 1 by visit and GINA step at study entry.

BUD/FORM maintenance and reliever therapy vs. higher maintenance dose ICS + SABA, difference at last visit as percentage predicted normal, adjusted for FEV1 at randomisation visit (95% confidence interval): Step 2, 2.18 (0.22, 4.14); Step 3, 3.58 (2.29, 4.87); Step 4, 3.83 (2.25, 5.40). BUD/FORM maintenance and reliever therapy vs. same maintenance dose ICS/LABA + SABA, difference at last visit as percentage predicted normal, adjusted for FEV1 at randomisation visit (95% confidence interval): Step 2, 1.29 (-1.29, 3.88); Step 3, 2.50 (1.25, 3.76); Step 4, 2.70 (1.24, 4.17). BUD/FORM maintenance and reliever therapy vs. higher maintenance dose ICS/LABA + SABA, difference at last visit as percentage predicted normal, adjusted for FEV1 at randomisation visit (95% confidence interval): Step 3, 0.22 (-0.82, 1.26); Step 4, 0.53 (-0.57, 1.64).
