Sustained visceral fat loss is associated with attenuated brain atrophy and improved cognitive function in late midlife.
Synthesis in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 4 registered trials, which are not on this 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.

Abstract
We examined whether long-term exposure to visceral-adipose-tissue (VAT) influences brain atrophy and cognitive performance years after lifestyle intervention. In the Follow-Interventions-Trials (FIT) project, 533 adults (age=61.4 y, 86% men) from four prior 18-24-month lifestyle randomized-clinical-trials underwent abdominal/brain magnetic-resonance-imaging (MRI)s and Montreal-Cognitive-Assessment (MoCA) testing 5-16 y after interventions. Lower VAT exposure, calculated by area-under-the-curve, from baseline, post-intervention, and follow-up, independently resulted in higher MoCA scores. VAT loss during intervention predicted higher brain volumes at follow-up, independent of weight loss. Among participants with three brain and VAT MRI scans, lower long-term VAT was associated with a slower rate of brain atrophy. These patterns were not observed for deep/superficial subcutaneous-adipose-tissues. Improved glycemic control parameters, rather than lipid or inflammatory markers, were mostly related to the favorable longitudinal brain outcomes. This long-term, large-scale intervention and follow-up MRI study suggests that sustained visceral fat loss, rather than weight loss, is linked to better cognition and attenuation of brain atrophy years later, mainly via improved glycemic control.
