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

backgroundEvidence continues to support the role of air pollution as a contributor to adverse outcomes in colorectal cancer (CRC); however, its effects on the mortality and disease progression transitions in CRC survivors, and the mediation pathways, remain uncertain.

methodsThis retrospective cohort study enrolled 3,357 patients diagnosed with non-metastatic colorectal cancer who underwent curative surgery at Sun Yat-sen University Cancer Center between 2012 and 2017. The annual average concentrations of PM
