Educational inequalities in dementia-related mortality using a multiple cause of death approach and their contribution to life expectancy differences in Spain.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
We examine dementia-related mortality in Spain from 2016 to 2021, focusing on its comorbidities and educational inequalities in life expectancy at age 60. Using a multiple cause of death (MCOD) approach, we assess how dementia-related mortality varies by education level and how these differences contribute to disparities in longevity. We used mortality data from the Spanish National Statistics Institute (INE) by level of education from 2016 to 2021 to analyse mortality from dementia-related diseases (ICD-10 codes: F01-F03, G30-G31) both as underlying cause of death (UCOD) and as MCOD (irrespective of their position within the death certificate). We estimated age-standardized mortality rates and used life tables and demographic decomposition techniques to assess the impact of dementia-related diseases on educational differences in life expectancy at age 60. Results showed that in 2016-21 MCOD dementia-related deaths accounted for 17% of all deaths occurring after the age of 60 (men: 11%; women 21%). The higher MCOD dementia-related mortality experienced by the lower educated group contributed 0.13 years (8.4%) to the total life expectancy gap at age 60 between the low and high education groups for men, and 0.26 years (22.7%) for women. Educational gradients in dementia-related mortality in Spain highlight the importance of disentangling risk factors from a socioeconomic perspective. Moreover, the MCOD approach provides a more realistic estimate of the impact of dementia-related diseases on life expectancy, bringing insights into the burden of ageing-related diseases.
