Abbreviation: EDE Equally distributed equivalent, INAB Incremental no-aversion benefit, INHB Incremental net health benefit, NHB Net health benefit, QALY Quality-adjusted life year, SES Socioeconomic status
aAll outcomes were averaged across 20 model trial runs with different random number seeds
bThe societal NHB incorporates QALY gain and QALY-equivalent net societal gain minus public sector opportunity costs (translated to QALY-equivalent using cost-effectiveness threshold of £30,000 per QALY gained) for each SES quartile. To account for the differing sizes of SES subgroups, per-capita societal NHBs were computed for each subgroup. The unweighted mean of the per-capita NHBs was then computed, effectively treating the subgroups as of equal size
