Survival, effect measures, and impact numbers after dementia diagnosis: a matched cohort study.
Article in Clinical epidemiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 16 papers, 1 of them a synthesis that pooled it.
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
backgroundKnowledge on survival after diagnosis is important for all stakeholders. We aimed to estimate the survival and life expectancy after a dementia diagnosis, and to quantify the impact of dementia subtypes on mortality.
methodsRetrospective matched cohort study using a linkage between a dementia-specific registry and two primary care electronic medical records databases. Between 1 January 2007 and 31 December 2015 there were 5,156 subjects aged 60 years and over registered by the Registry of Dementia of Girona and matched to 15,468 age-sex and comorbidity individuals without dementia attended by general practitioners in the province of Girona (Catalonia, Spain).
resultsThe median survival was 5.2 years (95% CI 5.0 to 5.4), the median life expectancy was 74.7 years (95% CI 71.9 to 76.5), and there were differences by gender. The mortality rate was 127.1 per 1,000 person-years (95% CI 121.6 to 132.7), and the hazard ratio for mortality in persons with dementia ranged between 1.63 (95% CI 1.52 to 1.76) for Alzheimer's disease and 2.52 (95% CI 1.90 to 3.35) for Parkinson-plus syndromes. There was one death per year attributable to dementia for every 18.6 persons with dementia, and for every 2.4 persons with dementia who die, one death was attributable to dementia.
conclusionThe prognosis after dementia diagnosis is conditioned by demographic and clinical features. Although survival is larger for women, they also experience a higher number of years of life lost. Parkinson-plus syndromes and dementia due to multiple etiologies are among the most malignant subtypes regarding mortality.
