Geographic variations and trends in percutaneous intervention for patients with and without acute myocardial infarction: A Japanese nationwide registry study.
Article in PloS one, 2025. 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
backgroundA previous study demonstrated that the per capita volume of percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) was relatively uniform across the 47 prefectures in Japan, while elective PCIs for stable coronary artery disease showed wide regional variation. However, contemporary data remain limited.
methodsThe Japanese PCI (J-PCI) is a nationwide prospective registry covering most of the procedures performed within the country. PCI procedures in 2019 and 2023 were included and divided according to the indications: AMI versus non-AMI. The patterns of PCI procedures performed for AMI and non-AMI across all prefectures in Japan were evaluated. The associations of the non-AMI/AMI ratio with population, area, and the number of PCI-capable centers per prefecture were also assessed.
resultsA total of 494,746 PCI procedures were analyzed. The ratios between the highest and lowest prefectures were 4.0-fold in non-AMI and 1.9-fold in AMI in 2019 and 4.2-fold in non-AMI and 2.0-fold in AMI in 2023. The non-AMI/AMI ratio was positively correlated with the ratios of the number of PCI-capable centers to population and area per prefecture.
conclusionsGeographic disparity was observed in the relative volume of PCI performed for AMI compared to non-AMI across Japan, potentially reflecting variations in the density of PCI-capable centers relative to the area and population of each prefecture.
