Figure 4.
Cost-effectiveness acceptability curve (cost per QALY gained with GClb vs RClb).
Notes: The acceptability curve reflects, for a certain WTP value, the percentage of the 1,000 ICER values obtained in the probabilistic analysis, which would be lower than that value and would be regarded as cost-effective.
Abbreviations: GClb, obinutuzumab + chlorambucil; ICER, incremental cost-effectiveness ratio; QALY, quality-adjusted life year; RClb, rituximab + chlorambucil; WTP, willingness to pay.
