Fig. 4From: Using the distance between sets of hierarchical taxonomic clinical concepts to measure patient similarityThe scatter plots of diagnoses prototypes of four subpopulations used for evaluation. The size of the circle is a relative scaled prototype score of the diagnosis code in the subpopulation. The color of the circle depends on the first letter of the ICD-10 code. a A subpopulation younger than 50 years old with HLOS shorter than 18 days. b A subpopulation younger than 50 years old with HLOS longer than 19 days. c A subpopulation older than 50 years old with HLOS shorter than 18 days. d A subpopulation older than 50 years old with HLOS longer than 19 daysBack to article page
