Prevalence of Abs against ZnT8 _178–186 and HERV-K Env_19–37 antigens in T1DM children. Plasma samples from T1DM patients, HCs, and patients at onset were tested with indirect ELISA assay. Abs against ZnT8 _178–186 (A,B) and HERV-K Env_19–37 (C,D) peptides. The dotted lines represent the cut-off values calculated by ROC analysis. The black bars represent median plus interquartile range. The Mann-Whitney p-value and the percentage of positive patients’ values calculated by the Fisher’s exact test are indicated in the upper section of the graph.
