Using Prenatal Tests to Estimate Pregnancy Start in Health Insurance Claims Data

"Using Prenatal Tests to Estimate Pregnancy Start in Health Insurance Claims Data" was accepted as a poster presentation at the 33rd Annual Meeting of the Society for Pediatric and Perinatal Epidemiologic Research (SPER). Due to the COVID-19 pandemic, the Annual Meeting was held virtually, excluding a poster session. In light of this, SPER sponsored a special issue of Paediatric and Perinatal Epidemiology including all abstracts that were accepted for presentation at the meeting to recognize research contributions.
