Data expressed as minimum and maximum mean value from all trials analyzed.
*For OLO/TIO 5/5 µg q.d. studies, TIO 5 µg q.d. used as comparator. †Differences were statistically significant at all time points up to Week 52 (at week 64, p=0.051). ‡52.6% patients in FOR/ACLI arm and 55.8% in SFC arm achieved MCID for SGRQ total score. §Significant reductions in the use of rescue medication versus placebo were also observed in the AUGMENT study (puffs/day not reported). ¶Approximate value.
LABA/LAMA: long-acting β2-agonist/long-acting muscarinic antagonist; FDC: fixed-dose combination; TIO: tiotropium; SFC: salmeterol/fluticasone; IND/GLY: indacaterol/glycopyrronium; q.d.: once daily; VI/UMEC: vilanterol/umeclidinium; OLO/TIO: olodaterol/tiotropium; FOR/ACLI: formoterol/aclidinium; b.i.d.: twice daily; FF/GP: formoterol fumarate/glycopyrrolate; SGRQ: St. George's Respiratory Questionnaire; NS: non-significant; NA: not available (no outcomes in any of the trials evaluated); MCID: minimum clinically important difference; NR: not reported (outcomes not reported in required units).
