Oxidative Potential of Atmospheric Particulate Matter: A Review of the Role of Metal-Organic Interactions, Mechanistic Insights, and Key Determinants.
Review in Environmental science & technology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Oxidative stress, resulting from antioxidant depletion or excessive reactive oxygen species (ROS) production, is a key mechanism linking ambient particulate matter (PM) exposure to adverse health effects. The oxidative potential (OP) of PM, a measure of inhaled PM's capacity to deplete antioxidants or generate ROS, is largely driven by transition metals (TMs) such as iron and copper. However, coexisting organic matter also modulates OP, both directly through its own redox activity and indirectly via interactions with TMs that alter redox cycling. This review synthesizes current understanding of TM-organic interactions and their influence on the OP of PM, as assessed by acellular assays. We discuss mechanistic insights, key determinants, and the complexity of these interactions. The importance of considering TM-organic interactions in evaluating aggregate OP from individual components and apportioning OP to specific chemical species is highlighted, with implications for mechanistic studies and health risk assessment.
