Figure 5

Histogram describing the distribution of similar cases per patient. For 165 patients with HCC (hepatocellular carcinoma) we calculated the number of cases which are rated as similar to the individual case by the risk assessment tool. The similarity search provides a two-peak distribution indicating there are groups of similar patients and singular cases which are quite different from the average. This may be caused by the small number of reference cases in the database, another explanation might be that there are patients with exclusive features which are very different from "the average patient".
