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

Background: Novel evidence suggests an association of wildfire smoke exposure with preterm birth (PTB). However, the mechanism and exposure timing of this association are poorly understood. Objective: We estimate the association of wildfire smoke on PTB phenotypes (spontaneous PTB [sPTB] and medically indicated PTB [mPTB]) as well as hypertensive disorders of pregnancy (HDP). Study design: Birth cohort data from singleton livebirths in California from 2007 to 2012 were combined with daily zip code-level estimates of wildfire smoke intensity. Satellite-based estimates of wildfire smoke plume boundaries and high-resolution gridded estimates of surface particulate matter 2.5 (PM Results: Of 2,548,347 eligible pregnant individuals, 86% were exposed to at least 1 day of wildfire smoke of any PM Conclusions: Our study found an association of wildfire smoke exposure with PTB, which was largely driven by sPTB.
