Further analysis revealed that GBP5 alone could discriminate between TB and ORD with an AUC of 0.93 (0.88–0.97) with a sensitivity of 90% and specificity of 86% (95% CI, 83–90%), thus also meeting the minimum TPP criteria for a triage test (Figure 2B, black line). The gene discussed is GBP5; the disease is tuberculosis.
