Placental transcriptome analysis in opioid-exposed versus non-opioid exposed pregnancies.
Article in Placenta, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
introductionOpioid exposure during pregnancy may significantly alter gene expression in the placenta, potentially disrupting its function and influencing fetal brain development. These alterations may contribute to adverse outcomes such as neonatal opioid withdrawal syndrome (NOWS). In this study, we aim to systematically investigate the changes in placental gene expression associated with maternal opioid exposure to better understand the underlying molecular mechanisms and their implications for fetal health.
methodsFresh placental tissue samples were collected from 18 opioid-exposed pregnancies and 26 non-opioid-exposed control pregnancies. Transcriptomic changes related to opioid exposure were assessed using RNA sequencing (RNA-seq).
resultsAmong the 16,172 genes detected, 55 showed differential expression (P DISCUSSION: Our findings suggest that opioid exposure during pregnancy may disrupt critical placental pathways, particularly those involved in immune responses. Future studies focusing on transcriptomic changes in specific placental cell types will be essential for fully understanding the structural and functional alterations in the placenta due to opioid exposure during pregnancy.
