Maternal prenatal immune activation associated with brain tissue microstructure and metabolite concentrations in newborn infants.
Article in medRxiv : the preprint server for health sciences, 2023. 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
Importance: Few translational human studies have assessed the association of prenatal maternal immune activation with altered brain development and psychiatric risk in newborn offspring. Objective: To identify the effects of maternal immune activation during the 2 Design: Prospective longitudinal cohort study conducted from 2012 - 2017. Setting: Columbia University Irving Medical Center and Weill Cornell Medical College. Participants: 76 nulliparous pregnant women, aged 14 to 19 years, were recruited in their 2 Exposure: Maternal immune activation indexed by maternal interleukin-6 and C-reactive protein in the 2 Main Outcomes and Measures: The main outcomes included (1) newborn metabolite concentrations, measured as N-acetylaspartate, creatine, and choline using Magnetic Resonance Spectroscopy; (2) newborn fractional anisotropy and mean diffusivity measured using Diffusion Tensor Imaging; and (3) indices of motor development assessed prenatally and postnatally at ages 4- and 14-months. Results: Maternal interleukin-6 and C-reactive protein levels in the 2 Conclusions and Relevance: Using a healthy sample, these findings demonstrate that levels of maternal immune activation in mid- to late pregnancy associate with tissue characteristics in newborn brain regions primarily supporting motor integration/coordination and behavioral regulation and may lead to alterations in motor development.
