Kaplan–Meier survival curve analysis of patients with CMV GI diseases. (A) Patients with different infected locations had no statistical difference in in-hospital mortality rates (log-rank p = 0.806). (B) Patients with immunocompromised status had significantly worse survival outcomes than those with immunocompetent status (log-rank p = 0.017). (C) Patients receiving Combo therapy had significantly better survival outcomes than others (log-rank p = 0.002). (D) Patients with different immune status and treatment courses had significantly different survival outcomes (log-rank p = 0.001). CMV, cytomegalovirus; CO, colon; Combo, combination of intravenous and oral antiviral therapy; ES, esophagus; GI, gastrointestinal; SI, small intestine; ST, stomach.
