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
backgroundGermany's aging population, driven by rising life expectancy and declining birth rates, has resulted in an increasing number of elderly individuals and various health-related challenges, with dementia being one of the most prevalent chronic diseases. Dementia is an umbrella term encompassing various medical conditions that cause progressive cognitive decline. It is linked to a substantially higher risk of death. However, data on the mortality of dementia in Germany are limited. Therefore, this study aims to estimate the all-cause mortality and mortality rate ratio (MRR) of individuals diagnosed with dementia between 2016 and 2021.
methodsThe age- and sex-specific mortality of people with dementia aged 65 and older, as well as the MRR between the years 2016 and 2021, were estimated using a partial differential equation. The estimation relied on the incidence and prevalence of dementia diagnoses among individuals covered by statutory health insurance and on mortality in the general German population, sourced from the German Federal Statistical Office.
resultsThe standardized overall mortality of individuals diagnosed with dementia increased slightly from 18,845 to 20,238 per 100,000, reflecting a rise of 7.4% between 2016 and 2021, with males typically showing higher rates. Overall, mortality increases exponentially with age. However, the age-related mortality rates remained relatively stable from 2016 to 2021, with only a slight upward trend. Individuals with dementia had a higher risk of death compared to individuals without dementia. Females diagnosed with dementia had up to 11 times higher risk of death compared to those not diagnosed with dementia at the same age, while for males it was up to 9 times higher. This difference was most pronounced in the 65- to 70-year age group, but diminished with increasing age.
conclusionsA dementia diagnosis is associated with increased mortality across all age groups, particularly among younger individuals, although the relative risk declines with age as dementia becomes one of several comorbidities. Targeted interventions to prevent dementia, delay onset, and prolong milder stages remain essential to reduce mortality of people with dementia.
