Figure 1. Kaplan-Meier survival curves of eosinophil and LDH in COVID-19 patients with chronic airway diseases. (A) Kaplan-Meier survival curve of eosinophil. COVID-19 patients with lower eosinophil counts had worse survival probability (p = 0.00079); (B) Kaplan-Meier survival curve of LDH. COVID-19 patients with higher LDH levels had worse survival probability (p = 0.04).
