Clinical inquiries. What nonpharmacological treatments are effective against common nongenital warts?

Cryotherapy has similar cure rates to topical salicylate (a pharmacologic therapy) for nongenital common warts (strength of recommendation [SOR]: B, based on systemic review of variable quality randomized trials). Duct tape may be equivalent to cryotherapy (SOR: B, based on a single randomized trial). CO2 laser, photodynamic therapy, pulsed dye laser (PDL), and Er:Yag laser therapies may also be effective for recalcitrant warts (SOR: C, based on observational cohort studies).
