Takeaway

  • Thermotherapy is associated with a nonsignificantly higher clearance rate compared with cryotherapy in patients with skin warts.
  • Scarring rate was higher.

Why this matters

  • The relative efficacy of thermotherapy vs cryotherapy was uncertain.

Key results

  • The clearance rate was 79.2% in thermotherapy patients and 58.3% in cryotherapy patients (P=.212).
  • Thermotherapy and cryotherapy patients had identical rates of postinflammatory hyperpigmentation or hypopigmentation (16.0%).
  • Thermotherapy patients had significantly increased scarring rates (20.0% vs 0%; P=.018).
  • Thermotherapy patients had nonsignificantly increased rates of posttreatment infection (8% vs 0%; P=.141) and local necrosis (4% vs 0%; P=.302).
