Plasma IL-21 levels are elevated in adults with T1D. (A) Plasma IL-21 levels in adults with established T1D and healthy controls. Mann-Whitney U-test was used for statistical analysis. (B) Correlation between age and log10-transformed plasma IL-21 levels was examined using Spearman’s correlation by pooling the data from both study groups and is expressed together with the P value on the plot. The elevations of the linear regression lines were significantly different between the study groups (P = 0.001). Medians and IQRs are shown in the (A).
