Main results for the three exercise interventions for preventing falls (showing health gain (QALYs), costs and ICERs for the lifetime of the modelled cohort, 95% UI within brackets)
| Baseline | QALYs gained/experienced | Net cost in NZ$ m | ICER in NZ$ |
| No intervention (comparator) with results reflecting the background costs and health status as the cohort ages | 4 090 000 QALYs experienced (3 860 000 to 4 290 000) | 42 200 (41 800 to 43 100) | Not applicable |
| Intervention | Incremental QALYs | Incremental costs | |
| Home-exercise programme for adults aged 65+ years | 47 100 (22 300 to 74 400) | 282 (139 to 380) | 6900 (2200 to 15 600) (US$4640) |
| Peer-led group-based exercise programme for adults aged 65+ years | 42 000 (21 800 to 65 600) | 535 (311 to 730) | 14 100 (5900 to 30 700) (US$9490) |
| Commercially provided group-based exercise programme for adults aged 65+ years | 42 300 (21 800 to 65 700) | 1950 (1370 to 2560) | 51 200 (25 400 to 1 07 000) (US$34 500) |
All results rounded to three meaningful digits.
ICER, incremental cost-effectiveness ratio; NZ, New Zealand; QALY, quality-adjusted life-years; UI, uncertainty interval.
