A study conducted by researchers was designed "to determine if application of duct tape is as effective as cryotherapy in the treatment of common warts." The researchers randomly divided
69
69 patients into two groups. The
35
35 patients in group 1 had their warts treated by applying duct tape. The
34
34 patients in group 2 had their warts treated by cryotherapy. Once the treatments were complete, it was determined that
69
69% of the patients in group 1 and
85
85% of the patients in group 2 had complete resolution of their warts. The researchers concluded that
cryotherapy
cryotherapy is significantly more effective in treating warts than
