Table 5. Cox proportional hazard ratios for times until death and until other poor health outcomes: ILAS.
| Frail state | Poor health Outcomes | ||||
|---|---|---|---|---|---|
| Number/death n | Death | Total | |||
| HR (95% CI) | p-value | HR (95% CI) | p-value | ||
| Robust | 970/2 | 1.00 (reference) | 1.00 (reference) | ||
| Non-mobility group* | 61/0 | N/A | 0.988 | 1.00 (0.31–3.25) | 0.999 |
| Mobility group† | 385/6 | 6.82 (1.37–33.85) | 0.019 | 1.67 (1.02–2.74) | 0.040 |
| Low activity | 166/1 | 3.76 (0.34–41.60) | 0.281 | 0.71 (0.25–1.99) | 0.514 |
| Non-mobility + Low activity | 14/0 | N/A | 0.994 | 1.55 (0.21–11.27) | 0.667 |
| Mobility + Low activity | 154/5 | 17.16 (3.33–88.51) | 0.001 | 2.67 (1.47–4.84) | 0.001 |
