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

backgroundWildfire smoke is a growing public health hazard yet there is limited evidence on its intermediate or long-term respiratory health effects. Studying the association between wildfire smoke exposure and indicators of impaired respiratory health such as persistent respiratory illness and respiratory symptoms can help elucidate the associated risk of developing chronic lung disease. We sought to determine whether wildfire smoke exposure is associated with medically-attended respiratory illness (MARI) and respiratory symptoms persisting beyond the acute wildfire period.

methodsThis was a population-based retrospective cohort study of adults without chronic lung disease aside from self-reported asthma, who reported living in a Northern California community affected by a wildfire in 2018. The primary predictor was mean daily wildfire-dominated fine particulate matter (PM
