Gestational and early postnatal protein malnutrition disrupts neurodevelopment in rhesus macaques.

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
Adequate nutrition during gestation is critical for fetal development, and deficits in protein are associated with neurological and behavioral impairments in offspring placing a significant burden on global health. Fetal and neonatal longitudinal magnetic resonance assessments of brain development spanning mid-gestation to 11 months of age were conducted in rhesus macaque (Macaca mulatta) (n = 22; 9 females) generated from an established nonhuman primate model of gestational protein reduction to ascertain the neurodevelopmental effects of reduced maternal protein intake. Structural abnormalities were identified in two reduced diet groups, in addition to age-dependent whole-brain volume deficits in the most severely reduced (50% vs. 33% reduction) protein cohort, primarily restricted to gray matter structures; i.e. cortical/subcortical gray matter and the cerebellum. Diffusion-weighted imaging revealed widespread postnatal reductions in white matter fractional anisotropy, concentrated in the corpus callosum for both reduced protein levels relative to control diet. Despite extensive neurodevelopmental alterations detectable by longitudinal imaging, early behavioral assessments conducted at 1 month revealed minor perturbations. These results highlight differential impacts of reduced maternal and infant protein intake on gray and white matter formation and organization, with potential implications for early motor development.
