title: Reporting bias in retrospective ascertainment of drug-induced embryopathy.
abstract: The rate of congenital malformations after first-trimester exposure to itraconazole was four times higher when ascertained retrospectively than prospectively (13.0 vs 3.2%, p=0.006). Reporting bias in retrospective studies should be acknowledged in interpretation of such data.
