Research topics clustered by mapping of co-occurrences of terms for publications on polymyxin resistance (2010–2019). Of the 6,413 terms, 42 terms occurred at least 200 times. The size of the circles represents the occurrences of terms in title/key. The largest set of connected terms consists of 42 terms in three clusters. The three clusters may be interpreted as: “relationship of polymyxin resistance with public health (red cluster, 16 items)”, “other drugs ineffective against multidrug-resistant organisms including polymyxin-resistant pathogens (green cluster, 14 items)”, and “genetics of polymyxin resistance (blue cluster, 12 items)”.
