I can't find the second two; the first one [1] is simply inconclusive; small sample sizes but no real effect. Crucially, this one compares duct tape to placebo

I can't find the second two; the first one [1] is simply inconclusive; small sample sizes but no real effect. Crucially, this one compares duct tape to placebo (a corn pad, which seems to be a foam ring that surrounds but does not cover the wart). The original study is from 2002, the first study linked above is from 2006. [1] https://pubmed.ncbi.nlm.nih.gov/17088514/ https://pubmed.ncbi.nlm.nih.gov/17088514/
