*179 of 285 (93 (64.14%) in the lens extraction and 86 (61.43%) in the standard care group) UK participants have complete cost and QALY data—above regression results are based on the data of these complete cases.
ICER, incremental cost-effectiveness ratio; QALY, quality-adjusted life years; Rc, ceiling ratio of willingness to pay per QALY gained.
