Identification of Novel RD1 Antigens and Their Combinations for Diagnosis of Sputum Smear−/Culture+ TB Patients

Figure 1

Scattergrams of normalized levels of the five antigens in TB patients and healthy controls. The values in ordinate represent the OD of the measured IgG levels of the antigen in patient serum samples. In each panel, the left scattergram shows IgG distribution in the whole TB population and the healthy control population. The right scattergram shows IgG distribution in three different TB populations (sputum smear+/culture+; sputum smear−/culture+; sputum smear−/culture−) and the control population.
