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

objectivesTo investigate the associations between maternal fine particulate matter (PM

designRetrospective observational cohort study.

settingA tertiary neonatal intensive care unit in China, 2016-2022.

participants2223 VPIs hospitalised during the study were enrolled after excluding infants with severe congenital malformations, those who abandoned treatment and those who died before discharge. Of these, 59.8% were male. PRIMARY AND SECONDARY OUTCOME MEASURES: We evaluated the effect of maternal PM

resultsAmong 2223 VPIs included in this study, 684 (30.8%) were diagnosed with BPD. Strong correlations were observed between PM exposure and BPD, with each IQR increase during the entire gestational period associated with ORs of 1.254 (95% CI 1.062 to 1.484) for PM

conclusionsMaternal PM exposure, particularly during the second trimester, is significantly associated with BPD in VPIs, with heightened vulnerability in males and infants with lower GA and BW. These findings underscore the need for prenatal air quality interventions and targeted monitoring of high-risk subgroups. Future research should explore PM-induced mechanisms of fetal lung injury and validate these associations in multicentre cohorts.
