Cost-effectiveness statistics
ICER: Intervention dominates
Net monetary benefit at £20,000: £222 (−584 to 1028).
  • Cost estimates were adjusted for randomisation variables; QALY estimates were adjusted for randomisation variables and baseline utility.

  • CI, confidence interval; ICER, incremental cost-effectiveness ratio; NHS, National Health Service; PSS, personal social services; QALY, quality-adjusted life year; SE, standard error.
