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

introductionAir pollution remains one of the most significant global health threats, affecting populations everywhere. Its widespread and persistent presence has long posed serious risks, and its far-reaching effects underscore the significant threat it poses to public health. Although numerous investigations have been conducted worldwide, their outcomes have remained inconsistent and lacked definitive conclusions. Therefore, this systematic review and meta-analysis sought to determine the association between air pollution and cognitive impairment across the globe.

methodsDatabases such as PubMed/MEDLINE, Jane, Science Direct, Cochrane Library, LIVIVO, CINAHL, Global Index Medicus, African Journals Online, Web of Science, HINARI, Semantic Scholar, Google, and Google Scholar were used to retrieve all the relevant articles. Data were analyzed using STATA 17 software to determine the pooled associations between air pollution and cognitive impairment with a 95% confidence interval using a random-effects model. Moreover, the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA 2020) guidelines were followed for this study.

resultFifty-four articles with 711,918 study participants were included in this meta-analysis to determine the association between air pollution and cognitive impairment. The findings of the study indicated that for every 1 µg/m
