Quantitative parameters are represented as mean ± standard deviation.
Abbreviations: PCR, polymerase chain reaction (number of positive samples); AG, antigen test (number of positive samples); CRP, C‐reactive protein; WBC, white blood cells; ICU, intensive care unit; ACE, acute cardiac events; ULN, upper limit of the norm.
a
Represents non‐normally distributed data.
b
Categorical parameters are represented as total n and percentage. Statistical test applied: Mann‐Whitney U test for non‐normally distributed data, t test for normally distributed data.
