Table 1. Detailed description of the characteristics of the study population. Abbreviations: CNS central nervous system SBP systolic blood pressure, PS peripheral saturation, RF respiratory frequency, TP body temperature. *: calculated by the EPI-CKD formula. Number of patients with missing data for each variable: age: 0, height: 10, weight: 17, body mass index: 24, first SBP: 2, lowest SBP: 8, PS: 4, RF: 4, TP: 8, Estimated glomerular filtration rate: 1, c-reactive protein: 9, Haemoglobin: 3, sodium: 2, potassium: 2, thyroid stimulating hormone: 37, alanine amino transferase: 8, glucose: 16, albumin: 2. Percentages of patients with a given condition (e.g. sodium < 132 mmol/l) were calculated by dividing the number of confirmed cases with the total number of patients in the population (200)
