Analyses of traditional pathologic factors for recurrence in 73 patients with stage I non-small cell lung carcinoma by log-rank test and Cox univariate analysis model. (A) Angiolymphatic tumor emboli (Angio.), (B) tumor differentiation (well-differentiated [WD] versus non-well-differentiated), (C) histology (squamous cell carcinoma versus non-squamous cell carcinoma), (D) substage (IA versus IB).

5. Fig 4
Kaplan-Meier recurrence-free survival estimates stratified by (A) combined ErbB-1+, -3+, (B) expression of three or more members of epidermal growth factor receptor family, (C) expression of ErbB-1+, -2+, -3+ or ErbB-1+, -3+, -4+. Difference between curves was analyzed by log-rank test and Cox univariate analysis.
