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

backgroundEpidemiological evidence on the risk of low Apgar score in newborns associated with ambient air pollutants, their joint associations, and sensitive exposure windows is limited. This study aimed to investigate the independent and joint associations between exposure to ambient air pollutants during different pregnancy trimesters and low Apgar score in newborns.

methodsTwenty thousand eight hundred ninety-four pregnant women were included in the prospective birth cohort in Shenzhen. Concentrations of PM

resultsSecond-trimester exposure to PM

conclusionsSecond-trimester exposure to air pollutants was associated with an increased risk of low 1-minute Apgar score, and PM
