Distribution of countries and institutions involved in MI/R injury research. A Network map of countries produced by the CiteSpace tool. B Number of publications, total citations, average citations, and H-index of the top 10 countries. C Visual network of institutions produced by the CiteSpace tool. The H-index indicates a given country has published at least H publications on MI/R injury from 2012 to 2021 with at least H citations each. Each node represents a country or institution, and the size of the node indicates the publication output of the country or institution. The lines between the nodes represent cooperation between countries or institutions, and the thicker the lines, the closer the cooperation becomes. The color of the node and line signifies different time intervals, and high centrality (> 0.1) is represented by nodes with purple rings
