Table 1 Baseline characteristics of the included patients from MIMIC III and IV. Descriptive statistics of the patient cohort in the experimental set are provided. Part of ICU observational data variables are expressed as Median (InterQuartile Range Q1–Q3), and binary or categorical variables are shown as Count (%). Specifically, ‘Length of Stay’ is abbreviated as ‘LOS’, ‘Heart Rate’ is abbreviated as ‘HR’, ‘Respiratory rate’ as ‘RR’, ‘Temperature’ as ‘Temp’, ‘Bicarbonate’ as ‘HCO3’, ‘Blood urea nitrogen’ as ‘BUN’, as ‘BPm’, ‘Diastolic blood pressure’ as ‘DBP’, ‘Systolic blood pressure’ as ‘SBP’, ‘Glascow coma scale tota’ as ‘GCS’, ‘Red Cell Distribution Width’ as ‘RDW’, and ‘White blood cell count’ as ‘WBC’
