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.

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.

Abstract

Poor indoor air quality (IAQ) in schools is of particular concern as it can negatively impact children's cognitive development, health, and well-being. Measuring IAQ-related parameters, assessing children's internal and external exposures, and developing solutions for reducing exposure are therefore critical to protecting children's health. The use of air purifiers can be a good mitigation strategy to improve IAQ in classrooms, but their association with health effects and cognitive outcomes in children remains unclear. The LEARN crossover study protocol aims to address this gap by evaluating the impact of a novel air purification intervention on IAQ, biomarkers of exposure, clinical health parameters, and cognitive performance in primary school children ( Clinical trial registration: https://clinicaltrials.gov/study/NCT06197477, Identifier NCT06197477.
