Field evaluation of a blood based test for active tuberculosis in endemic settings - Fig 2

<p>Accuracy matrix for the number of antigens used in the multiplex panel from 1 to 11 (selected <i>M</i>.<i>tb</i>. antigens), as analyzed by the Optimized Decision Tree algorithm. SN = Sensitivity, PPV = Positive Predictive value, NPV = Negative Predictive Value, SP = Specificity, TE = Test Efficiency, and MCC = Mathew Correlation Coefficient.</p

Blinded study in India: sensitivity and specificity compared to Pakistan, using 7 antigens.

Impact of the number of antigens on performance metrics determined by modified decision Tree algorithm.

<p>Results in two combined categories of TB patients (AFB⁺/Culture⁺ & AFB^-/Culture⁺) for sensitivity, positive and negative predictive values, test efficiency (TE) and Matthew Correlation Coefficient (MCC), and test sensitivity in individual categories of TB patients (AFB⁺/Culture⁺, AFB^-/Culture⁺, AFB^-/Culture^-), and test specificity (COPD patients and healthy group). Values shown are percentages.</p
