1 · What the graph read from 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.

2 · The registry

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: Emerging evidence highlights the potential role of environmental factors, particularly air pollution, in the development and progression of Alzheimer's disease (AD). Air pollutants may contribute to neurodegenerative processes through mechanisms such as oxidative stress, neuroinflammation, and disruption of the blood-brain barrier. Objective: This review aims to systematically evaluate global cohort studies investigating the association between long-term exposure to key air pollutants-specifically particulate matter (PM2.5), nitrogen dioxide (NO Methods: A total of 31 peer-reviewed cohort studies were included based on a structured search strategy. We analyzed epidemiological outcomes, exposure assessment methodologies, and geographic trends. Additionally, a bibliometric analysis was conducted using VOSviewer to identify major contributors and emerging research themes. Results: Findings indicate a consistent association between PM2.5 exposure and increased risk of AD, independent of genetic predisposition and lifestyle factors. Proposed biological mechanisms include oxidative stress, microglial activation, blood-brain barrier disruption, and amyloid-β accumulation. Bibliometric mapping revealed regional concentration of research in North America, Europe, and East Asia, with increasing global interest over the past decade. Conclusions: There is mounting evidence linking air pollution to Alzheimer's disease. Advances in exposure assessment have improved the accuracy of epidemiological findings. Public health policies targeting air quality control and further studies on molecular and early-life exposures are essential to mitigate the neurotoxic effects of environmental pollutants.
