Correction to: Elevated Level of Serum Interleukin-21 and Its Influence on Disease Activity in Anti-Neutrophil Cytoplasmic Antibodies Against Myeloperoxidase-Associated Vasculitis in the JICR by Junnan Xu et al. Journal of Interferon & Cytokine Research 2022;42(6): 290;DOI: 10.1089/jir.2022.0014

In the June, 2022 issue of Journal of Interferon & Cytokine Research, the article entitled Elevated Level of Serum Interleukin-21 and Its Influence on Disease Activity in Anti-Neutrophil Cytoplasmic Antibodies Against Myeloperoxidase-Associated Vasculitis in the JICR by Junnan Xu et al., requires correction.

The values presented in the abstract were originally published as:

(1324.2 ± 125.3 pg/mL vs. 704.2 ± 41.1 pg/mL, P < 0.001)

The values have been revised to:

( 1324.0 ± 812.4 pg/mL vs. 704.2± 266.3 pg/mL, P < 0.001)

The heading for the second column in Table 2 was originally published as: Range (maximum–minimum)

The heading has been revised to: Range ( minimum–maximum )

The minimum–maximum ESR, mm/h range presented in Table 2 was originally published as: 24.00–124.00

The range has been revised to: 24.00– 140.00

In Table 3, under MPO-ANCA, the first column head was published as: B

This has been changed to: β
