Steel-Dwass test analysis of between-group differences. ( a ) The median serum IP-10 level was significantly higher in the TAFRO-iMCD group than in the other 2 groups. ( b ) The median serum PDGF-AA level was significantly lower in the TAFRO-iMCD group than in controls and tended to be lower in the TAFRO-iMCD groups than in the iMCD-NOS group. The serum IL-10 ( c ), IL-23 ( d ), and VEGF-A ( e ) levels were significantly higher in the TAFRO-iMCD and iMCD-NOS groups than in the control group. Control: Healthy control, iMCD: iMCD-NOS, TAFRO: TAFRO-iMCD, IP-10: chemokine interferon γ-induced protein 10 kDa, PDGF-AA: platelet-derived growth factor -AA, IL: interleukin, VEGF-A; vascular endothelial growth factor-A, N.S: not significant.
