Data are median (IQR), n (%), where N is the total number of patients with available data. P values comparing the confirmed patients and the suspected patients are from χ² test, Fisher's exact test, or Mann‐Whitney U test. Lymphopenia, Patients with lymphopenia on admission. Nonlymphopenia, Patients with nonlymphopenia on admission.
