Brain regions with gestational age differences mediate cognition in adolescents born very premature.
Article in Communications biology, 2026. 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
Being born prematurely is known to have wide and diverse effects on neural development, some of which persist into adolescence. Currently, little research exists regarding the mediating and longitudinal effects of these neuronal differences into adolescence. Using ~2100 subjects from the Adolescent Brain and Cognitive Development study, a longitudinal cohort of adolescents (aged 10-14), identified as premature, and matched full-term peers, we conducted a canonical correlation analysis of their grey matter volume and fractional anisotropy. We also performed cross-sectional and longitudinal linear modeling with behavioral and cognitive measures and mediation analyses. Adolescents born more than 9 weeks premature showed reduced GM and increased FA in regions of the brain that are critical to attentional processes, memory, executive function, cognitive control, problem solving, and information processing. These differences mediated the relationship with cognition and persisted across four years of development. Neuronal changes associated with very premature birth are long-lasting and explain in part their lower cognitive functioning.
