Evaluation
WARTS, COMPLICATIONS
All patients were evaluated at the beginning of the study and at each follow-up visit. The final response was assessed after 4 weeks of the last session for any signs of clearance of the treated and adjacent warts and all complications were recorded. Moreover, two blinded dermatologists were asked to evaluate the response by scoring photos of treated lesions before therapy and 4 weeks following the last session. The observers were asked to score the degree of improvement in number and size of treated and adjacent untreated warts as follows: 0 = no change, 1 = less than 25% improvement, 2 = 25–50% improvement, 3 = 51–75% improvement and 4 = 76–100% improvement. Patient scores of 0 or 1 were considered as unresponsive.
