Fig. 2From: Mapping the landscape and structure of global research on nutrition and COVID-19: visualization analysisVisualization of the network of publications associated with nutrition and COVID-19 based on the titles/abstracts of the retrieved literature. Each node in the map indicates a term that appeared at least 50 times, and the size of a term's node is proportional to the number of times that the term appeared. Cluster analysis based on term cooccurrence showed three primary clusters (green, blue, and red). ‘Food security in the COVID-19 pandemic’ (cluster 1, green), ‘nutritional determinants and COVID-19 results’ (cluster 2, blue), and ‘changes in dietary habits during the COVID-19 pandemic and its consequences’ (cluster 3, red) are the three clustersBack to article page
