Fig. 2From: Clustering identifies endotypes of traumatic brain injury in an intensive care cohort: a CENTER-TBI studyTen models of each number of clusters between three to fifteen were created. The model with the highest log likelihood was chosen as the best model. This was repeated twenty times. Median, minimum, and maximum cluster similarity index (CSI, defined as the fraction of patients assigned to the same cluster in two models), of the twenty models were calculated. The median CSI is presented in Fig. 3Back to article page
