Table 6. Distribution of hospitalizations before and after vagus nerve stimulation surgery.

The table shows a significant increase in the number of patients with no hospitalizations (from 21 to 42) after VNS and a decrease in those with more frequent hospitalizations. This indicates that VNS therapy effectively reduces hospitalizations in patients with multifocal refractory epilepsy.
