The six most abundant differentially expressed proteins between groups. Differences in protein expression between PCR-verified COVID-19 infection (COV-POS), patients with respiratory symptoms but with > 2 negative polymerase chain reaction (PCR) tests for COVID-19 (COV-NEG) and healthy controls (HCO). Boxplots of COV-POS (orange), COV-NEG (grey) and HCO (blue) for A Alpha-1-acid glycoprotein 1 (ORM1), B Caspase-14 (CASP14), C Apolipoprotein 1 (APOA1), D Calpain 1 (CAPN1), E Pulmonary surfactant associated protein B (SFTPB), and F Transferrin (TF). Data are presented as individual values (black dots). Line in boxplots represents mean and the lower and upper boundary of boxplots representing 25th and 75th percentile with whiskers below and above boxes representing 10th and 90th percentile, respectively. Statistical significance was tested with ANOVA and Tukey’s honest significance test and defined as ****p < 0.0001, ***p < 0.001, **p < 0.01, *p < 0.05 and NS (p > 0.05)
