Figure 2. Dynamic changes of eosinophil counts and LDH levels in COVID-19 patients with chronic airway diseases. (A-D) Eosinophil counts increased over time in non-severe and severe COVID-19 patients with chronic bronchitis (n = 31), COPD (n = 18) and asthma (n = 10). (E-H) LDH levels decreased over time in non-severe and severe COVID-19 patients with chronic bronchitis (n = 31), COPD (n = 18) and asthma (n = 10). Values of non-severe and severe patients were presented with open and closed circles, respectively. Mann-Whitney U test was used. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, compared with the eosinophil counts or LDH levels between severe and non-severe patients.
