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

Global air pollution policies have drastically lowered anthropogenic emissions, yet climate change threatens regional air quality through poorly understood natural feedbacks. Extreme heat accelerates biogenic volatile organic compound and soil nitrogen emissions, fueling ozone and secondary organic aerosol formation. Although standalone impacts of these biogenic sources are documented, chemical interactions between co-elevated vegetation and soil fluxes remain unconstrained. Here we show that a temperature-driven synergistic mechanism between biogenic terpenoids and soil nitrogen emissions severely exacerbated secondary air pollution during China's unprecedented 2022 heatwave. Integrating ground observations, satellite data, and chemical transport modeling, we demonstrate that a massive surge in biogenic terpenoids enhances atmospheric oxidation capacity by generating reactive peroxy radicals. These radicals accelerate the conversion of soil nitric oxide to nitrogen dioxide without consuming ozone, driving a 21% regional ozone increase across the Yangtze River Basin and boosting secondary organic aerosol loads by up to 4 μg m
