Adverse pregnancy outcomes and lung function later in life: The CARDIA lung study.
Article in Respiratory medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundPregnancy events are linked to future maternal health, although relationships between adverse pregnancy outcomes (APOs) and maternal respiratory health are unknown.
methodsThis is a secondary analysis of CARDIA, a multicenter cohort study. We included all women who had delivered a live infant. APOs were defined as a history of ever having a small-for-gestational-age infant, preterm birth, gestational diabetes mellitus, or hypertensive disorder of pregnancy. Women were categorized as having no, one or >1 pregnancy with any APOs. Outcomes included year 30 lung function, annual change in lung function from year 20-30 and presence of radiographic emphysema at year 25. Adjusted linear regression was used to evaluate associations between APO category and percent predicted forced expiratory volume in 1 s (FEV
resultsAmong 657 women, those with >1 pregnancy with APOs had a significantly lower year 30 ppFEV
conclusionsA history of APOs may represent a novel, early indicator of worse lifetime maternal respiratory health, although larger studies accounting for multiparity and other important confounders are needed to confirm this finding.
