Descriptive Exploration of Features Among Infants With Prenatal Fentanyl Exposure in a Multisite Cohort of Maternal-Infant Dyads Affected by Opioid Use Disorder.
Article in Journal of addiction medicine. 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
objectivesA recent case series suggested a possible syndrome associated with prenatal fentanyl exposure. We described, among a cohort of maternal-infant dyads affected by opioid use disorder (OUD), the prevalence of these observed infant features.
methodsWe used data from MAT-LINK, a surveillance system compiling electronic health record (EHR) information from 7 US clinical sites on pregnancies affected by OUD between 2014 and 2021. We described the prevalence of EHR-documented prenatal fentanyl exposure and infant features of interest (cleft palate, corpus callosum abnormality, foot positioning deformities, genital anomalies, microcephaly, micrognathia, toe syndactyly).
resultsAmong 5053 maternal-infant dyads affected by OUD, 667 (13.5%; 95% CI: 13.0%-14.0%) had documented prenatal fentanyl exposure, including an over 20-fold increase from 2014 to 2021. Health insurance, prenatal care timing, and nonopioid substance exposures differed between dyads with and without documented prenatal fentanyl exposure. At least one feature of interest was documented for 406 (8.0%) infants, and at least 2 were documented for 0.7%. Among infants with at least one of these features, 18.9% (95% CI: 17.1%-20.8%) had documented prenatal fentanyl exposure, compared with 13.0% (95% CI: 12.5%-13.6%) of infants without any of these features.
conclusionsIn this perinatal OUD cohort, prenatal fentanyl exposure was more commonly documented among infants with at least one compared with none of these infant features. However, features were rare and contextual factors differed among dyads by prenatal fentanyl exposure status. Further analyses examining these infant features, while considering multiple exposures, are needed before substantiating a fetal fentanyl syndrome.
