Tracking biochemical indicators of air pollution exposure in acute cardiorespiratory emergencies: a scoping review.
Article in Frontiers in public health, 2026. 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
Background: Short-term ambient air pollution is a known trigger for acute cardiovascular and respiratory events. Biochemical markers help reveal pollution-induced physiological changes during emergency presentations, though evidence remains fragmented. Objectives: This scoping review mapped existing literature on short-term biochemical responses to air pollution in patients presenting acutely with cardiorespiratory conditions. Eligibility criteria: Eligible studies were human studies assessing at least one biochemical marker in people presenting to emergency departments after short-term exposure to outdoor air pollution. Sources of evidence: Five databases (PubMed, Scopus, Web of Science, Embase, CINAHL) were searched from 2000 to 2025. Charting methods: Data were extracted using the PCC framework and summarized in structured tables. Results: Twelve studies met criteria. PM Conclusions: The mapped evidence suggests that short-term air pollution exposure is associated with acute biochemical alterations. Standardized exposure windows, harmonized biomarker panels, and more detailed subgroup analyses are needed before these markers can support emergency-care pathways and environmental health policy.
