| T-SPOT.TB | TB-Ab | TB-DNA | ||||
|---|---|---|---|---|---|---|
| + | − | + | − | + | − | |
| TB group | 44 | 7 | 18 | 33 | 33 | 18 |
| Non-TB group | 7 | 33 | 0 | 40 | 9 | 31 |
Note: 1. Comparisons of the positive rate in the TB group and the non-TB group detected by T-SPOT.TB, TB-DNA and TBAb; χ2=11.79, 9.2462 and 8.4070; P=0.0012, 0.0024 and 0.0037
2. In the TB group, the comparison of the positive rate detected by T-SPOT.TB and TB-DNA, the comparison of that detected by T-SPOT.TB and TB-Ab, and the comparison of that detected by TB-DNA and TB-Ab; χ2=6.24, 4.78 and 10.89; P=0.013, 0.032 and 0.001
