|---|---|---|---|
| Walking at baseline | Walking at follow-up | 32 | 26 |
| Not walking at follow-up | 2 | 9 | |
| Not walking at baseline | Walking at follow-up | 10 | 3 |
| Not walking at follow-up | 6 | 13 | |
| Crude risk ratio (95% CI) | 1.48 (1.13–1.93) | 1.00 (reference) | |
| Crude odds ratio (95% CI) | 3.98 (1.56–10.17) | 1.00 (reference) | |
| Stratified risk ratio* (95% CI) | 1.48 (1.16–1.90) | 1.00 (reference) | |
| Stratified odds ratio* (95% CI) | 6.26 (1.98–19.75) | 1.00 (reference) |
