Table 3. Association of IAD with PAD in the total subjects and age subgroups.
| Exposure variables | Populations |
||
|---|---|---|---|
| Total subjects | Age < 62 years | Age ≥ 62 years | |
| Log10 (1 + IAD) (per 1 log unit) |
2.54 (1.13–5.69) P = 0.02 |
3.69 (1.08–12.55) P = 0.03 |
1.08 (0.56–2.09) P = 0.83 |
| Age (per 1year) |
1.07 (1.05–1.10) P < 0.01 |
1.07 (1.01–1.14) P = 0.02 |
1.08 (1.04–1.12) P < 0.01 |
| Log10 (1 + IAD) × Age (interaction term) |
— P = 0.04 |

The table gives odds ratios (95% confidence intervals) by multivariable logistic regression analysis in the total subjects and the subgroups stratified by the median age.
Abbreviations: IAD, inter-arm blood pressure difference; PAD, peripheral arterial disease.
