Prognostic analyses through odds ratio (OR) calculations for household contacts considering the interactions of the three prognostic factors: Mitsuda test, presence of BCG scar (sBCG), and salivary anti-lipoarabinomannan (LAM) sIgA.

Bold fonts were used to emphasize the significant values.

sBCG (−) = worse prognosis (0 cBCG) and (+) = better prognosis (1 and 2 sBCG).

Mitsuda (−) = worse prognosis (0–3 mm) and (+) = better prognosis (≥4 mm).

Mitsuda/sBCG (–) = worse prognosis (Mit < 4/sBCG-ID = 0) and (+) = better prognosis (Mitsuda ≥ 4/sBCG ≥ 1).
