Patients with mild symptoms (i.e., fever, cough, expectoration, and other upper respiratory tract symptoms), and without abnormalities, or with mild changes on chest radiography, were classified as non-severe types.

Severe pneumonia was defined by the presence of any of the following conditions: 1) significantly increased respiration rate (RR): RR ? 30 times/minute; 2) hypoxia: oxygen saturation (resting state) ? 93%; 3) blood gas analysis: partial pressure of oxygen/fraction of inspired oxygen (PaO2) /FiO2)?300 mmHg (millimeters of Mercury); or 4) the occurrence of respiratory or other organ failure that requires intensive care unit (ICU) monitoring and treatment, or shock
