Of note, we mathematically found that also markers like anti-Tpx IgG and/or anti-LAM IgA, which performed less well in Univariate analysis (Table 2), were valuable contributors in the Multivariate analysis (Table 3), as they complemented very well other well performing biomarkers, such as anti-PT-64 IgA and TB-LTBI IgG (Table 3). This evidence concerns the gene TPO and tuberculosis.
