Association of allostatic load with all-cause and cause-specific dementia: A prospective cohort study.
Article in Alzheimer's & dementia (New York, N. Y.). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
introductionAllostatic load (AL) serves as a valuable tool for objectively assessing the biological impact of chronic stress and has been implicated in dementia risk. This study aims to investigate the association between AL and all-cause dementia, Alzheimer's disease (AD), vascular dementia (VaD), and non-Alzheimer non-vascular dementia (NAVD).
methodsThis prospective study included 361,920 adults from the UK Biobank, with an observation period extending from March 13, 2006, to October 31, 2022, excluding participants with prior dementia diagnoses. AL was estimated through 10 biomarkers related to the dysregulation of metabolic, cardiovascular, and inflammatory systems. Diagnoses were based on the International Classification of Diseases, 10th Revision (ICD-10). We performed Cox proportional hazards models to assess the relationship between AL and dementia. Additionally, we conducted subgroup analyses for sex, Townsend Deprivation Index (TDI), and smoking, along with sensitivity analyses.
resultsThe median follow-up period was 12.88 years. Over the follow-up period, 6155 (1.70%) participants developed all-cause dementia, 2762 (0.76%) developed AD, 1316 (0.36%) developed VaD, and 3790 (1.05%) developed NAVD. In the fully adjusted model, high AL was associated with an increased risk of all-cause dementia (hazard ratio [HR]: 1.269, 95% confidence interval [CI]: 1.159-1.390), VaD (HR: 1.934, 95% CI: 1.569-2.384), and NAVD (HR: 1.253, 95% CI: 1.116-1.408). Women and non-smoking individuals with high AL were vulnerable to VaD, and the associations between AL and all-cause dementia were stronger in people with high TDI. DISCUSSION: AL is positively associated with an elevated risk of dementia, underscoring its effect as a risk factor in the neurodegenerative process that provokes dementia. Highlights: This study estimated allostatic load (AL) index through 10 biomarkers.The associations between AL and all-cause and cause-specific dementia were evaluated.Elevated AL is a risk factor for all-cause dementia and vascular dementia.
