Correlation analysis between asthma and clinical traits/cytokines in COVID-19 patients. a Correlation of asthma and clinical traits/circulating proteins in patients with COVID-19. The size of the dots represents the significance level of the correlation, with a “*” indicating p < 0.05. Correlation coefficients (r) are indicated by colour. b Network of asthma and clinical traits/circulating proteins correlations in patients with COVID-19. The colours of the lines indicate the correlation coefficients (r)
