Comparisons within TB patients.
T0 versus T2, T4, T6, T9, ; T0 versus T2, T4, T6, T9, ; T0 versus T2, T4, T6, T9, ; T0 versus T9, ; T0 versus T9, .
Results are shown as median values (25–75 percentiles). HCo: healthy controls. T0: time of diagnosis; T2, T4, T6: 2, 4, and 6 months after starting the specific anti-TB treatment; T9: 3 months after the end treatment completion. Comparisons for independent groups were made by the Kruskall-Wallis analysis of variance followed by post hoc test when applicable. Comparisons for related samples were performed by the Friedman analysis for variance.
