COVID-19 positive patients exhibited a clustered expression profile of exhaled breath proteins. Protein intensities of the 27 differentially expressed proteins were log10 transformed, normalized with a Z-score and displayed as colors ranging from blue to red with white boxes indicating missing values. Rows are clustered using Euclidean distance and cluster into three distinct expression profiles indicated by gap between rows. Samples are grouped into patients with 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)
