Prevalence and progress of underdiagnosis of probable dementia: a repeated cross-sectional study in 19 European countries.
Article in BMC medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundUnderdiagnosis of dementia remains a significant public health challenge in Europe, with nearly half of those meeting clinical criteria not receiving a formal diagnosis. Recent healthcare initiatives have aimed to improve diagnostic processes, but the extent of progress varies across countries.
methodsWe analyzed data of 10,402 participants from the Survey of Health, Ageing, and Retirement in Europe (SHARE) across 19 countries from 2011-2015 to 2015-2019. Underdiagnosis of probable dementia was defined as probable dementia (based on cognition score) without a confirmed diagnosis. Weighted logistic regression was conducted to examine temporal trends in underdiagnosis of probable dementia and to identify individual- and country-level predictors of progress in diagnosis.
resultsA significant reduction in underdiagnosis of dementia was observed between the two periods, consistent across most countries. Progress in diagnosis was modified by country-level factors such as number of psychiatrists, formal long-term care worker at home or institutions, and positron emission tomography and individual-level factors including age, education, retirement status, nursing home residency, multimorbidity, and healthcare utilization patterns.
conclusionsThe decreasing trend in underdiagnosis highlights the importance of targeted interventions including investment in psychiatric care services. Understanding remaining disparities is crucial for informing health policies and addressing inequalities to dementia diagnosis and care.
