Table 2. Diagnostic yield of the three different diagnostic modalities.
Variable | TBB*,† | BB | BW |
---|---|---|---|
Benign | 42/64 (65.6)‡ | 7/64 (10.9) | 14/64 (21.9)§ |
Malignant | 35/87 (40.2) | 11/87 (12.6) | 3/87 (3.4) |
Total | 77/151 (51.0) | 18/151 (11.9) | 17/151 (11.3) |
Values are presented as number (%).
*p<0.001, McNemar's test between diagnostic yields of TBB vs. BB. †p<0.001, McNemar's test between diagnostic yields of TBB vs. BW. ‡p=0.003, chi-square analysis between diagnostic yields for malignant vs. benign lesions. §p=0.001, chi-square analysis between diagnostic yields for malignant vs. benign lesions.
TBB: transbronchial biopsy; BB: bronchial brushing; BW: bronchial washing.
