- Initial sample size small (61) and then 9 lost to follow up and 1
excluded from study after losing study wart. Loss of 16% of patients
may be significant.2
- Follow up time of only 2 months is relatively short, as other studies
have shown recurrence up to 6 months.3
- Duct tape arm had no side effects compared to several observed side
effects in cryotherapy arm.
- Several studies have shown no real benefit of cryotherapy over simple
OTC topical treatments (salicylic acid),4 further supporting duct tape
which is less inexpensive and has fewer side effects than even OTC meds.
- Two-thirds of all common warts resolve spontaneously in 2 years so
is treatment really neccessary?
