Proteins altered in CACs incubated with asymptomatic patients’ serum compared with negatives and functional network. A Graphical representation of the label-free quantification (LFQ) intensities registered for several proteins altered in CACs + PCR (n:8) and CACs + IgG (n:8) compared to CACs + Neg controls (n:8). Differences were considered significant when p-values < 0.05. *p-value < 0.05, *p-value < 0.01, *p-value < 0.001. B Receiver operating characteristic (ROC) analysis of HSPA5, STAB1, RAB10 and TMP3 proteins in asymptomatic COVID-19 patients with area under curve (AUC). C Naïve Bayes classifier
