Fig 4 Disease-free survival by stage with 95% confidence intervals at 2-year intervals. Patients with sublobar resection (dashed lines) had similar disease-free survival compared with patients receiving lobectomy (solid lines) if they were stage IA (A; log-rank test, p = 0.308), but worse disease-free survival if they were stage IB (B; log-rank test, p = ).

Fig 5 Marginal and conditional estimates of overall survival by type of resection with 95% confidence intervals at 2-year intervals. When considered alone, sublobar resection conveys a worse prognosis for overall survival (A). The marginal effect of sublobar resection lowers 5-year survival from 54% in the lobectomy group to 40% in the sublobar group (log-rank test, p = ). However, when adjusted for other significant predictors, sublobar resection has no effect on overall survival. This is equally true for patients with limited (B) or extensive (C) node sampling.
