Is black carbon associated with cardiovascular and cancer mortality? Evidence from the Malmö Diet and Cancer Cohort.
Article in Global health action, 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
backgroundBlack carbon (BC) is an air pollutant of growing concern due to its adverse impacts on health and climate. Growing evidence suggests that BC could have a number of negative impacts on morbidity and mortality, but more evidence is needed.
objectiveThe objectives of this study are to quantify any associations between BC exposure and cause-specific (cardiovascular and cancer) mortality outcomes.
methodsUsing the Malmö Diet and Cancer Cohort linked with a high-resolution dispersion model, we examined the association between long-term exposure to locally emitted BC, nitrogen oxides (NO
resultsIn fully adjusted models, BC exposure was consistently associated with cardiovascular mortality (HR 1.15 [1.06-1.26] per IQR increase), an association that was stronger and more robust than for PM2.5 or NO
conclusionThis study shows associations between BC exposure and especially cardiovascular mortality, consistent with international evidence showing similar impacts. For cancer mortality, there were tendencies of an association with BC but less clear than for cardiovascular mortality. These findings suggest a unique role of BC in air pollution-related cardiovascular mortality and support the need for action on mitigation of air pollution in general and BC in particular.
