Impact of ambient fine particulate matter (PM
Article in BMJ global 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
backgroundAmbient fine particulate matter (PM
methodsUsing Global Burden of Disease 2023 data, this study analysed APMP-attributable deaths and disability-adjusted life years (DALYs) via absolute numbers and age-standardised rates. The multidimensional framework included joinpoint regression, age-period-cohort (APC) modelling, Das Gupta decomposition, disease spectrum ranking and Bayesian-APC projection.
resultsIn 2023, APMP caused 2.955 million deaths in BRICS (59% of the global total). Age-standardised mortality and DALY rates remained higher than global averages and increased since 1990, contrasting with sustained declines in the G7. Substantial heterogeneity existed: India's burden was heaviest and growing, China's remained high but stabilised, while Brazil and Russia achieved marked reductions. APC modelling revealed pronounced mortality increases in older ages (especially 95+ years in China and India). Decomposition identified population ageing as the key driver in BRICS, especially China; population growth and deteriorating epidemiological conditions under high exposure drove increases in India and South Africa. Leading APMP-attributable burdens in BRICS were ischaemic heart disease, chronic obstructive pulmonary disease and intracerebral haemorrhage, unlike in the G7 where Alzheimer's disease and other dementias ranked first. Projections indicate the BRICS burden will remain above the global average by 2050, with China and India continuing to bear severe burdens.
conclusionBRICS is the epicentre of global APMP-attributable burden. The widening gap with the G7 underscores divergent environmental health governance paradigms. Findings call for differentiated strategies within BRICS and enhanced transnational collaboration to curb APMP burden rises and bridge global environmental health equity gaps.
