Summary measure is n (%) for all categorical characteristics.

(*). Scar or parent report.

P value for comparison of all three groups. If P<0.05, P1, P2, P3 will be calculated.

P1: for comparison between confirmed TB and probable TB; P2: for between probable TB and TB unlikely and P3: for between TB unlikely and confirmed TB.
