Values are means ± standard deviations for IgG antibody in 20 TB patients treated with a standard drug regimen. Duncan's test for multiple comparisons of means was used to determine whether there were any significant differences between results for different durations of chemotherapy. The letters a and b indicate a significant difference (P < 0.05) between results for a given antigen.
