Table 4. Odds ratio for slow walking speed in participants with and without visual impairment.
| Participants | ||
|---|---|---|
| with visual impairment (n = 60) | without visual impairment (n = 2749) | |
| Slow walking speed (<1m/sec) | ||
| Unadjusted OR (95% CI) | 7.40 (3.36, 16.30) | 1.0 (ref) |
| P value | <0.001 | |
| Adjusted OR (95% CI) | 4.50 (1.87, 10.85) | 1.0 (ref) |
| P value | 0.001 | |
| Slow walking speed (≤0.8m/sec) | ||
| Unadjusted OR (95% CI) | 6.49 (2.46, 17.11) | 1.0 (ref) |
| P value | <0.001 | |
| Adjusted OR (95% CI) | 3.51 (1.21, 10.15) | 1.0 (ref) |
| P value | 0.021 | |
BCVA, best corrected visual acuity; OR, Odd ratio; CI, confidence intervals.
Adjusted OR is adjusted for variables (age, sex, BMI, smoking, and health conditions). BMI was categorized 3 by underweight (<18.5 kg/m2), normal weight (18.5–24.9 kg/m2), and overweight or obese (≥25.0 kg/m2).
