Neurodevelopmental challenges at age four following fetal exposure to maternal opioid maintenance treatment.

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
backgroundThe impact of intrauterine exposure to maternal opioid use disorder (OUD) and opioid maintenance treatment (OMT) on child development is not fully understood. This population-based cohort study investigated the neurodevelopmental and behavioral outcomes of four-year-old children prenatally exposed to maternal OMT, hypothesizing greater challenges compared to their same-aged peers in Finland.
methodsChildren with intrauterine exposure to buprenorphine±naloxone or methadone (n = 123) were compared with typically developing children (n = 434) using standardized language, motor-perceptual, and attention-behavioral skills screening tests. ICD-10 diagnoses for developmental and behavioral disorders were compared with national data from 50,457 Finnish children. Odds ratios (OR) and 95% confidence intervals (CI) were calculated to assess risks.
resultsChildren with prenatal OMT exposure exhibited significantly higher rates of developmental challenges as indicated by screening tests and ICD-10 diagnoses, including speech and language disorders, ADHD, conduct, emotional, and social disorders (F80, F90-94), with ORs ranging from 8.97 to 210.21. Additional risk factors included male sex (p < 0.001), methadone (p = 0.004), illicit drug exposure (p = 0.011), and domestic violence (p = 0.032).
conclusionChildren born to mothers with OUD and OMT face significantly elevated risks of developmental and behavioral challenges. Close monitoring, stable environment and early support for these children with multiple risk factors are crucial. IMPACT: This population-based cohort study demonstrates that children with in-utero exposure to maternal OMT are at high risk of neurodevelopmental, emotional and behavioral difficulties at age four. Our results particularly add new knowledge of specific domains (skills) in neurodevelopmental screening tests and ICD-10 diagnoses in these children. Beyond OMT, multiple additional risk factors such as fetal exposures to illicit substances or other harmful substances and postnatal environmental instability further compound the likelihood of later-life impairments. These findings emphasize the critical need for comprehensive follow-up, stable environment, and early interventions for this vulnerable group.
