Duct tape and warts

Are there differences in the efficacy of duct tape versus cryotherapy in the treatment of the common wart $($Arch Pediatric & Adolesc Medicine $156$: $971-974$; Focht et al$.,2002).$ To answer this question, $61$ participants between the ages of $3$ to $22$ years were random assigned to receive either traditional cryotherapy treatment or duct tape treatment for their wart. In the paper a table of the locatio of the wart is presented for each of the two treatment types.
