Unless otherwise specified, data are median, with the interquartile range in parentheses, and number and percentage for categorical variable.
BSA, body surface area; CK‐MB, creatine kinase‐MB; COPD, chronic obstructive pulmonary; COVID‐19, coronavirus disease 2019; CRP, C‐reactive protein; CT, computed tomography; Hs‐cTNT, high sensitivity cardiac troponin T; LDH, lactic dehydrogenase; NT‐proBNP, N‐terminal pro‐B‐type brain natriuretic peptide; RT‐PCR, reverse transcription polymerase chain reaction.
Data are expressed as the means ± standard deviation for continuous variables.
The clinical type of disease severity of Delta Variant of COVID‐19 was assessed according to the Chinese Center of Disease Control (CDC) criteria (32). The mild, moderate, and severe categories were assigned accordingly.
The white blood cell count, Hs‐cTNT, Nt‐pro BNP, LDH, CK‐MB, CRP, D‐dimer, and IL‐6 normal ranges below 9.5 × 109/L, 17.5 pg/mL, 100 ng/L, 250 U/L, 24 U/L, 10 mg/L, 0.55 mg/L, and 5.30 pg/mL, respectively, in our laboratory.
