Correlation analysis between M. tuberculosis antigen-specific IFN-γ responses to ESAT-6 protein and those to the ESAT-6/CFP-10 peptide pool in PBMC and matched PFMC from TBP patients (n = 281). (A) Correlation analysis between the numbers of SFCs to ESAT-6 in PBMC (x axis) and in PFMC (y axis). (B) Correlation analysis between the numbers of SFCs to ESAT-6/CFP-10 peptides in PBMC (x axis) and in PFMC (y axis). (C and D) Correlation analysis between the numbers of SFCs to ESAT-6 (x axis) and to ESAT-6/CFP-10 peptides (y axis) in PBMC (C) and in PFMC (D). The Pearson t test was used to analyze the correlation. The correlation coefficients (r) and P values are indicated.
