Pertinence

RésultatWell-controlled asthma weeks 34.4% vs 31.1% (OR 1.14, 95% CI 1.00–1.30, p=0.046); severe exacerbation rate reduced 64% vs as-needed SABA (RR 0.36, 95% CI 0.27–0.49).

Discussion et critique

Foundational evidence for GINA's recommendation against SABA-only therapy; PRN ICS-formoterol is the new standard for mild asthma.
