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

objectiveThis study aimed to investigate the influence of different obesity-metabolic syndrome (MetS) statuses on mild cognitive impairment (MCI) and to explore the modifying roles of related factors.

methodsData were obtained from the China Health and Retirement Longitudinal Study (CHARLS, 2011-2015) and a real-world cohort (RWC). Binary logistic regression and restricted cubic spline models were used to examine the associations between obesity, MetS, and MCI, adjusting for covariates. In the RWC, the effects of obesity-metabolic phenotypes on cognitive function were further explored using structural magnetic resonance imaging (MRI) to evaluate brain atrophy.

resultsA total of 6079 participants from CHARLS and 522 from the RWC were included. Each additional MetS component increased the risk of MCI in females aged < 60 and 60-70 years. Low high-density lipoprotein (HDL) levels in older males negatively affected cognition, and elevated fasting glucose was significantly associated with poorer cognitive performance. Metabolically unhealthy non-obesity (MUNO) and metabolically unhealthy obesity (MUO) were associated with higher MCI risk both in males and females, while metabolically healthy obesity (MHO) in males aged 60-70 years was also linked to increased risk. RWC further revealed that MHO, MUNO, and MUO groups exhibited varying degrees of brain atrophy compared with healthy controls.

conclusionFindings from both cohorts suggest that obesity and metabolic health jointly influence cognitive impairment risk. Structural MRI results highlight that metabolic dysregulation may exacerbate obesity-related neurodegeneration.
