The impact of population aging on the mortality rate of dementia among residents in Suzhou, China, 2004-2023.
Article in Journal of Alzheimer's disease reports. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: The global burden of disease research shows that the disease burden of dementia (including Alzheimer's disease and other dementias) is increasing. Objective: This study aims to analyze the trends of dementia deaths among residents in Suzhou and explore the impact of population aging on dementia mortality rates during the period from 2004 to 2023. Methods: The study utilizes demographic dementia mortality data of Suzhou's registered residents over the 20-year period for comprehensive analysis. Joinpoint regression analysis was employed to estimate the average annual percentage changes (AAPC) in indicators for dementia. Using the method of decomposing the differences of mortality rates to evaluate the contribution of population aging to dementia mortality. Results: The population composition ratios of aged ≥60 and ≥65 in 2023 were 25.70% and 20.24%, respectively; The number of dementia deaths from 2004 to 2023 was 24 014, and the average age of death caused by dementia increased from 79.74 ± 11.20 years old to 84.13 ± 8.49 years old. Dementia death age rose significantly over time, varying by gender. The crude mortality rate increased from 14.67/100 000 in 2004 to 21.55/100 000 in 2023, but the standardized mortality rate decreased from 9.16/100 000 in 2004 to 5.91/100 000 in 2023; The increase in the crude mortality rate of residents in 2023 was 213.66% attributed to the contribution rate of population aging. Conclusions: The overall crude mortality rate of dementia among residents in Suzhou is still on the rise, and population aging is a key factor.
