Influence on the diagnosis of distance from lesion to pleura
| Distance | EBUS-GS (n, %) | ENB-EBUS (n, %) | χ2 | P1 |
|---|---|---|---|---|
| d<1 cm | 18/25 (72) | 11/15 (73.3) | 0.008 | 1 |
| 1≤d<3 cm | 32/40 (80) | 4/9 (44.4) | 4.765 | 0.043 |
| d≥3 cm | 15/18 (83.3) | 2/2 (100) | 0.392 | 1 |
| χ2 | 0.921 | 3.221 | ||
| P2 | 0.636 | 0.151 |
Note that when the lesion was d≥1 cm and situated <3 cm from the pleura, the diagnostic rate of EBUS-GS (80%) was higher than the diagnostic rate of ENB-EBUS (44.4%).
