Least square mean improvements in mean FEV₁ from baseline in patients treated with BUD/FORM MRT or fixed-dose BUD, stratified by baseline reliever use (<1, 1–2 and >2 occasions/day). The error bars represent 95% CI. Statistical comparisons are for BUD/FORM MRT compared with fixed-dose BUD. BUD budesonide, CI confidence intervals, FORM formoterol, FEV ₁ forced expiratory volume in 1 s, MRT maintenance and reliever therapy. * +0.11 L (95% CI: 0.04, 0.17), p = 0.001; † +0.11 L (95% CI: 0.06, 0.16), p < 0.0001; ‡ +0.10 L (95% CI: 0.02, 0.17), p = 0.01
