Association of early life cardiovascular risk factors with grey matter structure in young adults in the United Kingdom: the ALSPAC study.

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
backgroundCumulative exposures to obesity, hypertension, and physical inactivity from midlife (40-65 years) onwards are three known cardiovascular risk factors for dementia and associated cerebral structural damage. Exactly how early in the lifespan sensitive periods for exposure to these risk factors begin is yet to be established, specifically with respect to onset of cerebral structural changes. We aimed to investigate whether cardiovascular risk across childhood and adolescence is already associated with cerebral structure in regions previously linked with dementia, during young adulthood.
methodsParticipants were selected from the Avon Longitudinal Study of Parents and Children (ALSPAC), a UK-based prospective cohort of young people, if they had participated in a neuroimaging sub-study (N = 862). We entered data from repeated clinical assessments into mixed-effects models to estimate baseline and rate of change in body mass index (BMI) and mean arterial pressure (MAP) between ages 7-17 years, and physical activity (PA) between 11-15 years. Linear models assessed whether cardiovascular risk factors were associated with grey matter macrostructural indices (cortical thickness, surface area, volume) in young adulthood (∼20 years).
findingsBMI was found to be associated with grey matter macrostructure in nodes of Default Mode Network previously found to show atrophy in dementia. Baseline BMI was associated with thickness of precuneus cortex and entorhinal surface area, whilst rate of change in BMI across childhood and adolescence was associated with thickness of parahippocampal and middle temporal gyri and inferior parietal cortex in addition to entorhinal and parahippocampal surface area. Further, we identified associations between baseline MAP and PA and entorhinal surface area. Exploratory whole-brain analyses revealed associations between baseline and rate of change in these cardiovascular risk factors and the cortical thickness, surface area, and volume of broader groups of cortical and subcortical regions.
interpretationFindings provide preliminary evidence that cerebral structural differences in regions linked to dementia in old age may be legacy of developmental differences associated with cardiovascular risk exposure during early life. This has relevance for lifespan models of dementia risk and timing of preventative interventions. Further work is required to generalise findings beyond this predominantly white, male, and middle-class sample to more diverse cohorts.
