|
age |
a vector of patient's age, male (1) or female(0) |
sex |
a vector of patient's gender |
num_comorbidities |
number of comorbidities (Chronic cardiac disease; chronic respiratory disease ( excluding asthma); chronic renal disease (estimated glomerular filtration rate ≤30); mild-to-severe liver disease; dementia; chronic neurological conditions; connective tissue disease; diabetes mellitus (diet, tablet or insulin-controlled); HIV/AIDS; malignancy; clinician-defined obesity.) |
respiratory_rate |
respiratory rate in breaths per minute |
admission_oxygen_saturation |
peripheral oxygen saturation on room air (%) |
glasgow_coma_scale |
a vector of Glasgow coma scale score |
urea |
urea concentration in mmol/L |
crp |
CRP in mg/L |
nosocomial |
symptom onset or first positive SARS-CoV-2 PCR more than 7 days after admission. yes as 1, no as 0 |
radiographic_chest_infiltrates |
radiographic chest infiltrates, yes as 1, no as 0 |
receiving_oxygen |
whether a patient is receiving oxygen when oxygen saturation measured |
lymphocytes |
lymphocyte count (* 10^9/L) |
func |
a vector of function specification: either mortality as 0 or deterioration as 1 |
