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

BackgroundAir pollution has been almost exclusively measured by region-level ambient exposure of particulate matter (PM) from government agencies (e.g., EPA), which does not capture the potentially large within-region variation and takes no consideration of human mobility in daily life. The use of region-level PM may have systematically biased the estimated associations with Alzheimer disease (AD).ObjectiveTo obtain pilot data on person-specific digital measurements of exposure to PM and volatile organic compounds (VOC) and to correlate them with AD biomarkers, including plasma and cerebrospinal fluid (CSF) analytes and amyloid and tau positron emission tomography (PET) signal, and to generate hypotheses about these correlations.MethodsFifty nine older participants underwent a 7-day digital collection of exposure to PM and VOC by Atmotube Pro, a validated wearable air quality sensor. Person-specific levels of PM and VOC were correlated with AD biomarkers. Sample sizes for future studies to detect the observed correlations were estimated.ResultsThe first functional principal components (FFPC) of 7-day exposure to PM and VOC captured 75% to 86% of the total variation. The FFPC of PM
