| NOR | OHT | p | OH | p | |
|---|---|---|---|---|---|
| Vascular diseasea | 1 [ref] | 0.743 [0.563—0.979] | 0.035 | 1.157 [0.9—1.487] | 0.254 |
| Low walking speedb | 1 [ref] | 1.332 [1.009—1.758] | 0.043 | 1.002 [0.778—1.292] | 0.985 |
| Hand-grip strength, /1 kg | 1 [ref] | 1.051 [0.799—1.382] | 0.722 | 1.447 [1.070—1.956] | 0.016 |

| Severe impairment in MMSe* | 1 [ref] | 1.629 [1.024—2.591] | 0.039 | 1.317 [0.781—2.221] | 0.301 |
NOR Normal orthostatic response, OHT Orthostatic hypertension, OH Orthostatic hypotension, MMSe Mini-Mental State examination. aVascular disease was a composite of stroke, peripheral arterial disease, coronary heart disease or carotid stenosis, bWalking speed lower than 0.8 m/s was considered low
Multivariate analysis was performed after adjustment for age, sex, resting systolic blood pressure and diabetes by using logistic regression for qualitative variables and general linear model for quantitative variables with the NOR group as reference. Results are Odds Ratio [IC 95%]. *Reference group was mild impairment in MMSe (≥ 20)
