BP: blood pressure; HR: heart rate; SATS: hemoglobin saturation with oxygen.

Value format is mean (SD). ICD-10 (Tenth Revision of International Classification of Diseases) specifies codes for diseases and diagnoses, where for each cluster, the most frequent code corresponds to the following: cluster −1 (unclusterable patients), 4, 5 = sepsis; cluster 0 = acute tonsillitis, unspecified; cluster 1 = lower abdominal pain; cluster 3 = chronic obstructive pulmonary disease with (acute) lower respiratory infection; cluster 6 = chronic ischemic heart disease.

Bold values are the highest value per feature.
