The weight of junk food: Smaller hippocampal, amygdala, and prefrontal volumes in adolescents-The Cogni-Action Project.

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
Most studies investigating diet-brain relationships in youth focus on single foods. Whether the joint consumption of multiple food groups is associated with neuroanatomy during adolescence remains largely unexplored, particularly outside high-income countries. In this cross-sectional study, 61 Chilean adolescents (11.6 ± 1.07 years; 42.6% girls) underwent T1-weighted MRI. Volumes of total gray matter, hippocampus, amygdala, and selected prefrontal regions were extracted. Dietary intake was assessed using the Global Food Quality Index questionnaire. Confounder-adjusted linear regressions examined individual food group-brain associations, with correction for multiple comparisons. Canonical correlation analysis (CCA) was used to identify multivariate food group-brain covariation with permutation-based inference. Univariate analyses showed a significant inverse association between pastry consumption and hippocampal volume (β = -0.402, 95% CI: -0.571 to -0.228, adjusted R
