ROC curves of T-lymphocyte subsets, ESR and CRP for assessing disease severity of UC patients. A: ROC curves of T-lymphocyte subsets (CD3⁺HLA-DR⁺T cells, CD8⁺T cells, CD4⁺/CD8⁺ ratio and CD4⁺CD25⁺T cells). B: ROC curves of CRP and ESR. C: ROC curve of the combination of CD3⁺HLA-DR⁺T cells and CRP. ROC, receiver operating characteristic; ESR, erythrocyte sedimentation rate; CRP, C-reactive protein
