Randomized Controlled Trial Multicenter Study Comparative StudyEVerT: cryotherapy versus salicylic acid for the treatment of verrucae--a randomised controlled trial.
To compare the clinical effectiveness and cost-effectiveness of cryotherapy using liquid nitrogen versus patient daily self-treatment with 50% salicylic acid for the treatment of verrucae (plantar warts). ⋯ There is no evidence for a difference in terms of clearance of verrucae between cryotherapy and salicylic acid (at both 12 weeks and 6 months), number of verrucae at 12 weeks and time to clearance of verrucae. Cryotherapy was associated with higher mean costs per additional healed patient compared with salicylic acid.
