OR values and 95% confidence interval (CI) were presented only for significant associations;
*
OR is calculated for arterial hypertension presence (no/yes) within the two groups;
**
includes: multiple sclerosis, neurodevelopmental disorders, peripheral vestibular syndrome, myasthenia gravis, history of head trauma, etc.;
***
includes: motor deficit+sensory manifestation, motor deficit+language impairment, etc.
