Table 2. Predictors of better visualization of the segmental plane by indocyanine green (ICG) fluorescence during thoracoscopic anatomical segmentectomy.
| Variables | P value | HR | 95% CI |
|---|---|---|---|
| %FEV1.0 | |||
| <70 | 0.77 | 1.32 | 0.21–8.22 |
| SI | |||
| >800 | 0.04* | 4.63 | 1.09–19.71 |
| BMI | |||
| >24 | 0.59 | 0.71 | 0.21–2.42 |
| LAA (%) | |||
| >1.0 | 0.01* | 5.64 | 1.46–17.44 |
Values were calculated by multiple logistic regression analyses; P value was significant at <0.05; *, better visualization was defined as ÄIntensity >20. HR, hazards ratio; CI, confidence interval; %FEV1.0, ratio of forced expiratory volume in 1 s to forced vital capacity; SI, smoking index; BMI, body mass index; LAA, low attenuation area.
