Fig. 4 — Risk factors for pulmonary LELC PFS The Univariate Cox regression analysis revealed that positive serum EBV-DNA, distant lymph node invasion (N2 and N3), advanced clinical stage (stage III and IV) and receiving radiotherapy were risk factors for the PFS in pulmonary LELC patients (a). However, the subsequent multivariate Cox regression model identified only the positive serum EBV-DNA was the independent PFS predictor (b). The median time for the positive serum EBV-DNA patients was 20.0 months (Green line; 15.5 months - 24.5 months), much short than that in the negative group (Blue line; 71.8 months; 95% Confidence Interval: 15.5 months - 24.5 months; P = 0.003)
