Air quality and presence of air ventilation systems inside waterpipe cafés in North Carolina.
Article in Tobacco control, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAfter North Carolina (NC) fire inspectors detected unsafe carbon monoxide (CO) levels inside several waterpipe cafés, the state fire code was amended to include provisions regulating waterpipe cafés, adding a requirement for air ventilation. These regulations apply to new buildings constructed after 1 January 2016, but can be enforced for older buildings where there exists a distinct hazard to life. We measured air quality at a sample of waterpipe cafés before and after the starting date of this regulation and collected information on presence of air ventilation.
