Subjective response and satisfaction
Most participants (69/88; 78% [68%–86%]) reported a subjective improvement from baseline at their last follow-up; 9/88 (10% [5%–19%]) reported no change and 4/88 (5%) a worsening. The remaining 6 (7%) could not answer the question since they had a broken stimulator (n = 2) or the stimulator was turned off for varying reasons (no more attacks (n = 1), no effect (n = 1), unknown (n = 2)).Most participants would also recommend (70/88; 81% [70%–87%]) this treatment to other patients; the majority would even make a strong recommendation (52/70, 74% [48%–69%]). Only 2 (2%) participants would not recommend ONS and 14/88 (16%) did not have a (strong) opinion.
