  1. OPQoL-Brief Older People’s Quality of Life brief questionnaire, EQ-5D-3 L EuroQoL EQ-5D 3 Level instrument and ASCOT Adult Social Care Outcomes Toolkit instrument, IQR Interquartile range, SD Standard deviation
  2. aEQ-5D-3 L and ASCOT utility scores and OPQoL summary scores were first power transformed to follow a normal distribution (using the square transformation) before converting them into Z scores
  3. bBased on discussions within the team and evidence from the literature, a positive relationship was hypothesised between quality of life (as measured by the OPQol-Brief, EQ-5D-3 L and ASCOT) and being younger [55, 70–73], being male [55, 73], living alone [74], having been born in Australia, a higher educational level [73, 75], having informal carer support [74] and higher self-reported general health [71]
