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

Mounting evidence supports associations between air pollution and noise exposure and cardiovascular events; however, the relationships at low exposure levels and for stroke outcomes remain uncertain. The aim was to investigate the associations between environmental exposures over 1-year and 10-year periods and both stroke severity and stroke type in a registry-based cohort including people with stroke residing in a low-pollution area of Sweden. Patients with stroke admitted to the Sahlgrenska University Hospital from 2014 to 2019 were included. Stroke severity was assessed with the National Institutes of Health Stroke Scale and stroke types were ischemic and hemorrhagic. Annual residential environmental exposures (road traffic noise (L
