Synthesis in BMJ paediatrics open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundPreterm birth (PTB) is a major global health issue, causing substantial newborn morbidity and mortality. Limited literature is available on the association between prenatal exposure to heat and air pollution (particularly, particulate matter 2.5 (PM
methodsA systematic search of numerous databases (Pubmed, Embase, Scopus and grey literature) for peer-reviewed articles published between 2010 and 2024 in LMIC was done using PM
resultsHeat exposures were associated with elevated incidences of PTB, especially during the first and third trimesters (OR=1.29 and 1.39, respectively). PM
conclusionThe results point towards a consistent adverse effect on the exposures studied (PM PROSPERO REGISTRATION NUMBER: The study protocol for this review was registered with PROSPERO-CRD42024563329.
