Abbreviations: ICER, incremental cost-effectiveness ratio; QALY, quality-adjusted life-year; SAVR, surgical aortic valve replacement; TAVI, transcatheter aortic valve implantation.
a
Incremental cost = average cost (TAVI) – average cost (SAVR).
b
Incremental effect = average total effect (TAVI) – average total effect (SAVR).
c
ICER = incremental cost/incremental effect
