Fig. 1From: Increased efficacy of regularly repeated cycles with OnabotulinumtoxinA in MOH patients beyond the first year of treatmentChange in percentage of HI (upper) and AC (lower) from T6 to T18 compared to baseline. Our observational results confirmed that already after 2 treatment cycles the HI was powerfully reduced of 22 % vs the baseline value and it kept consistently reducing overtime down to 34 % at T18 (at the cycle 7). This clinical improvement was further raised up by a simultaneous marked trend of reduction in AC vs the basal status that reached a 67 % at T18Back to article page
