SDHD and pulmonary tuberculosis: As shown in Figure 6A, there was no correlation between the TTP (the number of days has been shown to be inversely related to the mycobacterial yield in the specimens) and the individual serum anti-PGL-Tb1 antibody level (R2 = 0.0007, p = 0.5449), or the anti-ESAT-6/CFP10 antibody level (R2 = 0.0005, p = 0.6013) among the groups of HIV-uninfected and HIV-unknown pulmonary TB patients.
