2 Fig 1 Graphic representation of the cumulative hazard function for each variable of the survival model: disease-free interval (DFI) of ≤12 months (blue line) or >12 months (green line), carcinoembryonic antigen (CEA) level ≤5 ng/mL (blue line) or >5 ng/mL (green line), laterality (unilaterality, blue line; bilaterality, green line), and pN status (NX-0, blue line; N1-2, green line). The x-axis represents the time (months) elapsed from the first pulmonary metastasectomy date to the final event (death/censured). The y-axis represents the logarithm of the cumulative hazard function ln [–ln(S)], with S = survival function. The parallel distribution of the curves over time supports the assumption of hazard proportionality. (LML = log minus log.)

3 Fig 2 Verification of the log-linear hypothesis through the graphic representation of residuals. The x-axis stands for the patients, and the y-axis represents the differences between the observed and expected values. Each dot symbolizes a patient. The fact that residuals are well balanced around the origin allows us to verify the log-linear hypothesis. (CEA = carcinoembryonic antigen.)
