Diagnostic accuracy, treatment and prognosis of myocardial infarction: an 11-year follow-up of a community-based cohort of 0.5 million Chinese adults.
Article in BMJ public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Introduction: Myocardial infarction (MI) is a major cause of premature death and disability in China, but available data on diagnostic accuracy, treatment and prognosis of MI cases remain limited. Methods: The China Kadoorie Biobank enrolled 512 000 adults (mean age 51 years, 59% women) from 10 (five urban, five rural) areas between 2004 and 2008. Medical records were sought on 37 159 reported first incident ischaemic heart disease (IHD) cases occurring before 2018 for adjudication. Diagnostic accuracy and risks of recurrent MI, stroke, heart failure and all-cause mortality were assessed for reported and adjudicated cases of MI and all IHD. Results: Among 19 135 adjudicated IHD cases, 10.2% (n=1948) had MI, with diagnostic accuracy of 98% for MI and 93% for all IHD. Use of guideline-directed (antiplatelet, lipid-lowering, antihypertensive and anticoagulant) medications in the hospital was high (93% MI; 83% all IHD), but differed by hospital tier and area. Use of coronary revascularisation was low (39% MI; 10% all IHD), even in higher tier hospitals. The 28-day case-fatality was sixfold greater for MI than all IHD (12.0% vs 2.0%) and higher in older cases and in women, residents in rural areas, but comparable by hospital tier. Disparities in 5-year mortality rates persisted for both MI and all IHD, by age, sex, area and hospital tiers. Conclusions: This large community-based prospective study demonstrated high levels of diagnostic accuracy for MI and all IHD in Chinese adults, but also identified disparities in treatment and outcomes that should be prioritised in future prevention strategies.
