title: Silver nitrate may be far superior to podophyllin in clearing HPV external anogenital warts.
abstract: Longitudinal data from a case series indicated that clearance rates (95% CIs) of anogenital warts (AGW) by silver nitrate (n = 14) and podophyllin (n = 34) were 93% (79.35, 100) and 14.7% (3, 27) respectively; and RR, 6.31 (95% CI 2.77, 14.37, p = 0.052), relative benefit increase, 532% (410, 654), and NNT, 1 (1, 2). The total effort needed US$28(BB$56) vs US$598 in 1-3 vs 1-37 visits to achieve one successfully treated patient respectively. While subject to the errors of an open, non-randomized case series, silver nitrate was highly efficacious and cost-effective and should replace podophyllin at the Winston Scot Polyclinic.
