In addition, patient age, lowest oxygen saturation (SPO2), hypertension, CLD1, chronic lung disease (CLD2), chronic kidney disease (CKD), and the levels of red blood cell, hemoglobin, hs-CRP, total bilirubin (TBIL), DBIL, aspartate aminotransferase, ALP, urea nitrogen, creatinine, cystatin C, cardiac troponin I (cTnI), and myoglobin were associated with the risk of death in the hospital (Table 4).
