Figure 3From: Prognostic impact of ZAP-70 expression in chronic lymphocytic leukemia: mean fluorescence intensity T/B ratio versus percentage of positive cellsAnalysis of ZAP-70 concordant and discordant cases among ISO-, T- and T/B Ratio-methods (test set). (A) Venn diagram depicting concordant and discordant cases, as obtained by merging the ZAP-70 positive cases determined by ISO-, T- and T/B Ratio-methods. (B) Kaplan-Meyer curves obtained comparing TTT of patients affected by CLL expressing ZAP-70 according to T/B Ratio-method (73), or expressing ZAP-70 according to either ISO- or T-methods (30).Back to article page
