Significance of group differences was tested using the Kruskal-Wallis test and effect sizes ε 2 and P -values are indicated above. Only group differences (analysed Dunn’s multiple comparison test) within each subgroup (SARS-CoV-2 infection, SARS-CoV-2 vaccination or negative/naïve) are shown, asterisks indicate a significant difference between groups after correction for multiple comparisons (21) using the two-stage linear step-up procedure of Benjamini, Krieger and Yekutieli. Data are shown as boxplots (boxes represent 25th to 75th percentiles with medians indicated by the horizontal lines, whiskers represent minimum to maximum) with individual data points (circles).
