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

Despite the recent increase in the intensity and frequency of wildland fires in the United States, there is limited investigation into the impact of wildland fires on pregnancy-related mortality and morbidity. This study examined associations between maternal exposure to wildland fire smoke and severe maternal morbidity (SMM), or potentially life-threatening complications related to pregnancy or delivery, in a population-based cohort of California birthing people between 2007 and 2018. We measured pregnancy smoke-day burden using the Hazard Mapping System smoke product and wildland fire-specific fine particulate matter (PM
