For patients randomized to the duct tape arm, a supply of standard duct tape was provided. The first piece of duct tape, cut as close to the size of the wart as possible, was applied to the wart in the clinic by nursing personnel. Patients or their parents were told to leave the tape in place for 6 days. If the tape fell off, parents were instructed to reapply a new piece of tape. At the end of the 6 days, they were told to remove the tape, soak the area in water, and then gently debride the wart with an emery board or pumice stone. The tape was left off overnight and was reapplied the following morning. The treatment was continued for a maximum of 2 months or until resolution of the wart, whichever came first. Patients in the duct tape arm were requested to return to the clinic every 4 weeks, if the wart was still present, for nursing personnel to remeasure the wart and record results on the data sheet.
