Serum concentration of sPD-1 and its correlation with IFN-γ concentration and platelet count. (A) Serum concentrations of sPD-1 in healthy subjects and ITP patients before and after treatment. Peripheral blood was collected from all patients and healthy subjects and subjected to ELISA assay. *, P < 0.05. (B-C) Correlation analysis of (B) IFN-γ concentration or (C) platelet count with serum concentration of sPD-1 in ITP patients before treatment. Correlation was analyzed using Pearson correlation analysis.
