Value of CXCL9, CXCL10, and CXCL11 levels for predicting HIV CD4⁺ T-cell count. a ROC curves for CXCL9, CXCL10, CXCL11, and a combination panel of three chemokines, in predicting CD4⁺ T-cell count at 1-year-infection. AUC values were used to evaluate CD4⁺ T-cell count at 1-year-infection and the point with the maximum sum of sensitivity plus specificity was defined as the cutoff value. b Kaplan–Meier curves for CXCL9, CXCL10, CXCL11, and the combination panel of three chemokines. Patients were divided into high expressers (above the cutoff value) and low expressers (below the cutoff value), according to the cutoff value for chemokine expression. CD4⁺ T-cell count reaching ≤ 500 cells/μL was considered as the end point for follow-up. p values for curves provided on graphs
