As a new concept in clinical research,the real world research(RWR) has attracted the attention of researchers in the world with its unique advantages. This research mainly analyzed it through visual methods,the specific steps were as follows. Firstly,the Chinese Biomedical Literature Database,China National Knowledge Infrastructure,Wan Fang Database,Medline and EMbase were searched and RWS were included,414 articles in Chinese and 2 158 articles in English were included in this research after layer-bylayer screening; secondly,the main information was extracted and sorted by BICOMS 2 software and generated its co-occurrence matrix; the network relationship diagram was drawn by Net Draw software; the cluster analysis was carried out by using g CLUTO software;finally,this research results show that the numbers of domestic and foreign literatures have shown an overall growth trend,but compared with foreign countries,China's research on the real world started late,the overall strength of research was not as good as abroad;and the domestic and foreign research on the real world was uneven in the region,the research in China was mainly distributed in developed provinces and cities,such as Beijing,Guangdong,Shanghai,etc,and there was a lack of close cooperation between provinces and cities; the foreign research are mainly distributed in developed countries such as the United States,the United Kingdom,Germany,et al; the cooperation between countries was relatively close. And the hotspots and core directions of domestic and foreign research were also different. This research was intended to provide reference for the further research of Chinese researchers through the current description of the themes and capability of the real world research in the world.
