Abstract Since the Natural Index was proposed in 2014, research has progressively increased on existing indicators, but scientometric analysis based on basic data is relatively scarce. Scientific quantitative analysis is based on publications in Natural Index journals in the field of global medical research. Based on the theories of co-word analysis and co-occurrence network, scientific measurement tools such as BICOMB and Ucinet are used to analyze the social network structure of research hotspots of the past two years. Additionally, the gCluto software is used for biclustering the word-article matrix to explore research frontiers. This research reveals the hotspots of global medical research, provides a reference for the development direction of the field, and analyzes the advantages and disadvantages of the Natural Index in the evaluation of scientific research.
