Variable Importance in Projection (VIP) represents the contribution score of the proteins that mostly contribute to the differentiation within the different COVID-19 severities and the control group. The red and blue boxes on the right indicate the relative amounts of the corresponding protein in each group under study. Horizontal and vertical red lines are delimiting the proteins with VIP value above 1.
