Does pneumonia increase the risk of dementia and cognitive decline? A systematic review and meta-analysis.
Synthesis in Annals of medicine, 2025. 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
objectiveThe link between pneumonia and elevated risk of dementia and cognitive decline is still unclear. This study aims to evaluate the link between pneumonia and the subsequent risk of developing dementia.
methodsMEDLINE (
resultsTen studies were included, encompassing a diverse population sample. Pooled analysis demonstrated a significant correlation between pneumonia and increased risk of dementia (HR = 1.738; 95% CI: 1.358 to 2.225), with substantial heterogeneity across the studies (I
conclusionsThis meta-analysis suggests that pneumonia is associated with a significantly higher risk of developing dementia. These findings underscore the need for diligent monitoring and preventive strategies for patients recovering from pneumonia, particularly among the elderly, to mitigate potential cognitive decline.PROSPERO registration number: CRD42024520631.
