Figure 4. Comparison of medication use between groups before and after radiosurgery.

Figure 4

Medication use before and after radiosurgery was made between both groups of treatment. A significant association was found among RGZ and DREZ patients when comparing medication use before and after radiosurgery (p=0.004 for RGZ and p=0.002 for DREZ). Both groups showed an increase in patients not using any type of medication after radiosurgery and decreased medication use after the treatment.

Abbreviations: DREZ, dorsal root entry zone; RGZ, retrogasserian zone.
