a
Patients were excluded from analysis if they were dead on arrival, died on day 1 of hospitalization, or lacked survival status. Patients described by the authors Meselson and Andrews were excluded because they lacked sign, symptom, and treatment data [2, 13]. Patients included in this analysis could have received other treatment, including antimicrobials.
b
Ventilated or intubated or respiratory rate > 30.
c
Vasopressors or systolic blood pressure <90 mm Hg.
