Baseline Characteristics of Patients
| Variables | Optimal group (n = 376) | Displacement group (n = 52) | P value |
|---|---|---|---|
| Age (yr) | 62.2 (55.1, 68.6) | 59.4 (52.9, 69.1) | 0.550 |
| Sex (M/F) | 192 (51.1)/184 (48.9) | 23 (44.2)/29 (55.8) | 0.356 |
| Height (cm) | 162.7 ± 8.5 | 162.5 ± 9.6 | 0.870 |
| Weight (kg) | 63.6 ± 11.1 | 71.3 ± 11.9* | < 0.001 |
| BMI (kg/m2) | 24.0 ± 3.3 | 26.9 ± 3.1* | < 0.001 |
| Obesity | 118 (31.4) | 39 (75.0)* | < 0.001 |
Values are presented as median (Q1, Q3), number (%), or mean ± SD. Optimal group: patients who exhibited DLT migration ≤ 15 mm after LDP, displacement group: patients who exhibited DLT migration > 15 mm after LDP. DLT: double-lumen endobronchial tube, LDP: lateral decubitus positioning, BMI: body mass index, Obesity: patients with BMI ≥ 25 kg/mm2. *P < 0.05, compared with the optimal group.
