Cumulative incidence of recurrence, cumulative incidence of lung cancer-specific death, cumulative incidence of death without recurrence and cumulative incidence of all death of all included patients. (A) There was no significant difference in cumulative incidence of recurrence between patients who underwent segmentectomy vs. lobectomy (P = 0.135). (B) There was no significant difference in cumulative incidence of lung cancer-specific death between patients who underwent segmentectomy vs. lobectomy (P = 0.908). (C) There was no significant difference in cumulative incidence of death without recurrence between patients who underwent segmentectomy vs. lobectomy (P = 0.442). (D) There was also no significant difference in cumulative incidence of all death between patients who underwent segmentectomy vs. lobectomy (P = 0.796).
