ROC curve analysis. Based on the clinical classification of specimens into TB or non-TB, hyplex® TBC results were analysed at different cut-off values regarding the diagnostic performance. Therefore, the rate of false-positive PCR results (100% minus specificity) was plotted against the sensitivity at cut-off values of 0.100, 0.200, 0.300,0.325, 0.350, 0.375, 0.400, 0.500, 0.700 and 0.800, corresponding to the optical densities of the ELISA read-out.
