Applicability of randomized controlled clinical trial (RCT) results to ‘real world' situations is dependent on the comparability of trial participants to general patient populations. A full disclosure of criteria employed for trial enrollment is necessary for clinicians to assess generalizability. We sought to assess both the impact on generalizability and the disclosure rate of enrollment criteria for 32 major HIV RCTs in the AIDS Clinical Trial Group (ACTG) and Community Programs for Clinical Research on AIDS (CPCRA) trial networks.Eligibility criteria were compared in complete protocols to criteria listed in publications from these 32 NIH-funded HIV RCTs. We then applied these criteria to the Women's Interagency HIV Study (WIHS), the largest cohort study of HIV-infected women in the US.When applied to WIHS, eligibility criteria from protocols excluded 0–67.6% (median 42%) of WIHS participants (50.6% excluded from ACTG trials). Eligibility criteria in publications excluded 0–62% (median 19.6%) of WIHS (21.2% excluded from ACTG trials). The number of women in WIHS seemingly ineligible for trial participation per enrollment criteria listed in publications averaged only 60% of those actually excluded based on the protocols.We found that HIV RCT eligibility criteria excluded a large proportion of a representative cohort of HIV-infected women from trial participation. Furthermore, trial publications are not fully reflective of protocols in terms of disclosing eligibility criteria. Standardization and full disclosure of trial methodology will allow clinicians and researchers to more fully assess the generalizability of findings to their patient populations.
