(a) Survival curves among participants stratified by TB Progression Score. TB Progression Score 1 (n = 4) and Score 2 (n = 2) are included in Score 3 due to small number of cases. The survival curve of Score 3 was different with statistical significance from that of Score 4 and Score 5 (P = 0.022, P < 0.001, respectively).

(b) Survival curves among participants stratified by the presence of TB progression. TB progression group increased the risk for all-cause mortality (adjusted HR = 1.68; 95 %CI = 1.21–2.34, P < 0.001). Median OS were 11.56 years (95 %CI; 10.62–12.08) for TB progression group and 13.92 years (95 %CI; 13.30 – not reached) for No TB progression group, respectively.
