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

The rising prevalence of cognitive decline and dementia imposes substantial burdens on individuals, families, and society. Air pollution has increasingly been linked to adverse cognitive outcomes, but findings vary across pollutants, study designs, and exposure-assessment methods. This review summarizes epidemiological evidence on ambient air pollution and cognitive outcomes among older adults, identifies research gaps, and outlines priorities for future investigation. PubMed was searched through February 2025 for peer-reviewed, English-language observational studies published from January 2000 onward that examined ambient air pollution and cognitive outcomes among adults aged 50 years and older. A total of 36 studies met the inclusion criteria. Fine particulate matter (PM
