  • a The cutoff value was set at 2.0 U/ml. Results are presented as numbers of positive subjects/total number of subjects (percentages). The mean anti-TBGL titers ± SDs (units per milliliter) for patients with far advanced and moderately advanced cavitary lesions were 16.9 ± 16.9 and 15.3 ± 19.9, respectively. Those for patients with far advanced, moderately advanced, and minimally advanced noncavitary lesions were 12.2 ± 20.0, 9.3 ± 15.0, and 4.6 ± 9.4 U/ml, respectively. The values for patients with cavitary lesions were significantly different from values for patients with noncavitary lesions (P < 0.01).
