Maternal and infant health during the COVID-19 pandemic - A Pennsylvania Study Protocol.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPregnant people are vulnerable to more severe outcomes of COVID-19 compared with their non-pregnant counterparts. Research is needed to systematically test the degree to which COVID-19 during pregnancy increases the risk for adverse maternal, perinatal, and infant health and development outcomes and whether social determinants of health or psychological/psychosocial health outcomes confound or intensify the risk. This protocol paper describes a prospective cohort study using electronic health record (EHR) and patient-reported data from four large health systems in Pennsylvania to examine neighborhood, social, and health factors predicting COVID-19 and its severity, birth weight, gestational age, and vaccination among pregnant people to 12 months postpartum.
methodsOur study will be conducted with two aims. Aim 1 will combine maternal and infant clinical data and neighborhood data from four health systems in Pennsylvania participating in a PCORI-supported clinical research network. The cohort will include all people who were pregnant between June 2019 and May 2025, along with linkage to their newborn delivery records. In Aim 2, a subset of pregnant people from the Aim 1 cohort will be recruited to participate in a series of surveys from pregnancy to one year postpartum. Survey instruments will be developed to collect patient-reported health and social information as well as patient-centered outcomes depicting whether and how the COVID-19 pandemic is impacting pregnant people and their newborns. Survey data will be collected during pregnancy and at one, six, and 12 months postpartum. Survey data will be linked with data from Aim 1 for analysis.
resultsEthical approval has been obtained at all sites. Subcontracts and data use agreements have been established. EHR data across health systems are being collected and curated. Surveys have been developed and recruitment and retention procedures implemented. Recruitment for the survey aim of the study began in July 2023 and is ongoing. DISCUSSION: This study will advance multi-site research involving pregnant people across diverse communities in a time of public health crisis. Data from this study will provide additional evidence of the impact of the COVID-19 pandemic on pregnant people and their infants. Findings will help guide future clinical and public health practices in pandemics for pregnant people.
