The NIH condom report: the glass is 90% full.

for the workshop. In addition, a panel of 28 people was chosen from a spectrum of backgrounds and ideologies to help craft the report. The workshop itself was attended by 180 interested individuals. The ground rules for the report were made clear from the outset. The panel examined only those peer-reviewed, published articles included in the presentations at the workshop. This limitation ensured that the independent scientific evaluation that occurs prior to publication was inherent in all of the data considered. While this approach allowed a certain quality control, it meant that several bodies of data (e.g., those available but unpublished, or those published but deemed unacceptable by the speakers) were not included in the full set of information considered by the panel. Nonetheless, an impressive array of 138 peer-reviewed articles that had been published by the time of the workshop were the basis for the NIH report. The report was limited to evaluating the effectiveness of male latex condoms used during penile-vaginal intercourse. It examined evidence on eight STIs—HIV, gonorrhea, chlamydia, syphilis, chancroid, trichomoniasis, genital herpes and genital human papillomavirus. The evaluation methodology was extensive, considering both the efficacy (ideal use) and the effectiveness (typical use) of the condom. The quality of the study design, the ascertainment of exposure (e.g., consistent condom use), the laboratory measures of outcome (e.g., STIs) and the adequacy of statistical analytic approaches were examined.
