Costs are reported in AUD. LY indicates life years.
*In line with the text, observed costs and survival incorporate predicted values beyond the observed intermediate endpoints, they are labeled as ‘observed’ values because they reflect the effects of the observed intermediate endpoints.
†Standardized costs and survival are estimated as observed minus expected values.
