Outcomes and costs observed over the complete period (trial-based and Markov models). All ranges are 95% confidence intervals, unless otherwise stated. 95% confidence intervals were derived from the probabilistic sensitivity analysis. FF: fluticasone furoate; UMEC: umeclidinium; VI: vilanterol; ITT: intention-to-treat; NICE: National Institute for Health and Care Excellence; LY: life year; QALY: quality-adjusted life year; ICER: incremental cost-effectiveness ratio.
