Extended Data Fig. 2: COVID severity is associated with blood levels of inflammatory cytokines.

a) Pearson correlation between patient age and COVID severity. b) Pearson correlation between patient age and duration of hospitalisation. c) Pearson correlation between comorbidity score and COVID severity. d–h) Pearson correlation between levels of IL-6, TNF, IL-1B, IP-10 and Protein S with COVID severity. i) Pearson correlation between age and levels of S100β. Dashed lines represent 95 % confidence intervals. Data in d-i were analysed by partial correlations with age, sex, and comorbidities as covariates. Multiple comparisons were controlled for by Benjamini-Hochberg correction.
