M = male.

F = female.

RF = cooled radiofrequency.

VNS = visual numeric pain scale (0-10 cm).

VNS prior RF between groups (8.46 ± 1.7 versus 9.24 ± 0.6) p > 0.05.

VNS prior RF compared at 3 weeks

and at 12 months post-RF among groups: 7 patients:

prior compared to 3-week and 12-month after RF (prior versus 3-week, p < 0.01);

(prior versus 12-month, p < 0.01);

(3-week = 12-month, p > 0.05).

Metamizole daily consumption (g) prior RF

and at 3-week: 7 patients: prior compared to 3-week

and 12-month after RF (prior versus 3-week, p < 0.05);

(prior versus 12-month, p < 0.05);

(3-week = VNS 12-month, p > 0.05).
