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.

Abstract

Particulate matter was shown to significantly affect children's cognition through intermediate-term to long-term exposure; however, whether and to what extent air purification can improve the neurodevelopment of schoolchildren remains unclear. We conducted a randomized, controlled, double-blind, crossover trial for cognitive health among primary children aged 10-12 years through a multi-setting, mid-term air-purification intervention in Henan Province, China. The intervention and control groups received alternative true or sham purification in classrooms and bedrooms in a random manner. The two intervention phases (76 days) were separated by a washout period of 88 days. Among 57 participants, air purification reduced personal exposure to PM
