Contraception

Publication bias is the selective publishing of favorable or statistically significant results. This practice, over time, distorts the medical literature by depicting inordinately optimistic outcomes for treatments and interventions. ⋯ Mandatory trial registration, as instituted by the International Committe of Medical Journal Editors (ICMJE), should reduce publication bias by improving the ability to identify all trials pertaining to a specific intervention. Contraception endorses the views of the ICMJE and will now require registration of all prospective trials.
