1 · What the graph read from it

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.

2 · The registry

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

backgroundAdipose tissue and the central nervous system regulate each other, but the interactions between body fat composition and brain health remain unclear.

methodsTo investigate this, we conducted Mendelian randomization (MR) analyses to explore the causality between body fat composition, brain volume, intelligence, cognitive performance (CP), and 19 neuropsychiatric diseases using six body fat measures. We performed cross-trait meta-analysis and colocalization analysis for body mass index (BMI) with Alzheimer’s disease (AD) and Parkinson’s disease (PD).

resultsOur findings show that higher body fat composition is associated with smaller grey matter volume, reduced intelligence and CP, increased risks of 10 neuropsychiatric diseases, and decreased risks of others. Additionally, certain brain diseases exert causal effects on body fat. We identified a novel AMDP1-containing genomic locus shared between BMI and PD. Adenosine signaling was highlighted as a cross-talking pathway with opposing effects on PD and BMI-related phenotypes.

conclusionsThese results highlight the bidirectional fat-brain axis and suggest the need for disease-specific weight management strategies.
