| Variables | LN metastasis (n = 268) | Invasiveness (ly/v/pl) (n = 336) | ||||
|---|---|---|---|---|---|---|
| OR | 95% CI | p value | OR | 95% CI | p value | |
| SUVmax | 1.06 | 1.01–1.11 | 0.03 | 0.96 | 0.88–1.05 | 0.20 |
| CD | 0.91 | 0.74–1.12 | 0.38 | 1.04 | 0.97–1.12 | 0.30 |
| MD | 1.23 | 1.01–1.50 | 0.02 | 0.84 | 0.76–0.90 | <0.001 |
| C/T | 1.05 | 1.01–1.09 | 0.01 | 0.98 | 0.97–0.99 | 0.006 |
C/T: CD/T; CD: maximal consolidation diameter evaluated with lung window setting; T: total tumor diameter evaluated with lung window setting; CI: confidence interval; LN: lymph node; ly: lymph vessel invasion; MD: maximal diameter evaluated with mediastinal window setting, OR: odds ratio; pl: pleural invasion; SUVmax: maximum standardized uptake value; v: vascular invasion
