Incomplete and inconsistent reporting of maternal and fetal outcomes in infertility treatment trials

Abstract

Pregnancy outcomes and adverse outcomes in infertility trials are reported to varying extents; for example, 35% of clinical trials reported no information on pregnancy loss, only 43% reported adverse events during the preconception treatment period, and only 7% reported any serious adverse events. Incomplete reporting limits the value of these studies in counseling patients on the risk-benefit ratio of treatment to themselves and their infants.
