Figure 1: Differentially expressed inflammation- and immune response-related proteins pre- and post-COVID-19 in ice hockey players.A: Heatmap showing differentially expressed proteins among athletes pre- and post-COVID-19, as well as post-COVID controls; B: Principal Component Analysis (PCA) of ice hockey players pre- and post-COVID-19; C: Scattered boxplot and heatmap of protein CCL11 (***: adjP=0.0035); D: Volcano plot of differentially expressed proteins measured by OLINK multiplex assays. Welch 2-sample t-test was used to compare pre- and post-COVID-19 athlete samples (confidence level 0.95). Correction for multiple testing done by Benjamini-Hochberg method. Statistically significant proteins shown in red (adjP <0.05); E, F: Ratio of significantly different proteins for different immune response and inflammation process networks to all proteins measured) in pre- (E) and post-COVID-19 athletes (F). Abbreviations: adjP, adjusted P value; Ctrl, control group; IH, ice hockey players; NS, non-significant.
