Multivariable analysis for OS for ESR population can be seen in Table 4. Age (p < 0.0001, HR = 1.034), and male sex (p < 0.0001, HR = 1.506) were significantly associated with OS. OS was significantly better than Whites in the Other Race (p = 0.0051, HR = 0.555) and Other Asian groups (p = 0.012, HR = 0.736), but it was similar in all other ethnic groups. As compared to Connecticut, worse survival was noted in California, Greater Georgia, Kentucky, Louisiana, and Utah. OS was not income dependent. Insured patients had a better OS than those on Medicaid (p < 0.0001, HR = 1.385). Married patients had a better OS than divorced (p < 0.0001, HR = 1.301), widowed (p < 0.0001, HR = 1.292), and single patients (p = 0.0015, HR = 1.121). Increasing tumor size (p < 0.0001, HR = 1.016) and T2 vs T1 (p < 0.0129, HR = 1.107) had a worse OS. Only the right lower lobe location was associated with survival (p < 0.0089, HR = 1.132). In comparison to patients with adenocarcinoma, large cell carcinoma, NSCLC-NOS, and squamous cell carcinoma were associated with a worse OS (p < 0.0011 to <0.0001, HR = 1.15–1.381). Using well-differentiated tumors as a reference, all other tumor grades were associated with a worse OS (HR = 1.572–1.846). Segmentectomies (p < 0.0090, HR = 1.235), pneumonectomies (p < 0.0001, HR = 1.782), and wedge resections (p < 0.0001, HR = 1.301) were associated with a worse OS than (bi)lobectomies. Patients who received radiation (p < 0.0001, HR = 1.36) experienced worse OS. Number of nodes examined was associated with better OS (p < 0.0001, HR = 0.984). Compared to year 2007, those patients diagnosed in 2010 and 2012 had significantly better OS.
