Finally, we also reported the absolute numbers of True Positive (TP), False Positive (FP), True Negative (TN) and False Negative (FN) samples classified based on the EGFR mutation status of tissue biopsy: TP are samples positive at both TB and LB, TN are samples negative at both TB and LB, FP are samples positive in LB but negative in TB, FN are samples negative in LB but positive in TB. The gene discussed is EGFR; the disease is tuberculosis.
