From: Early and strong antibody responses to SARS-CoV-2 predict disease severity in COVID-19 patients
Correlation of the early antibody levels (3–14 DPS) with the disease severity. a Anti-SFL3 IgG and anti-SFL IgA levels in the groups of patients with severe/moderate (n = 35) vs mild disease (n = 16). Box plots show median and 25th and 75th percentile, upper whisker—Q3 + 1.5 IQR, lower whisker—Q1−1.5 IQR; dots represent individual samples. b ROC curves showing the discrimination between patients with severe/moderate vs mild disease based on early anti-SFL3 IgG and anti-SFL IgA levels
