From: Clinical efficacy and safety of maintenance therapy for advanced non-small cell lung cancer: a retrospective real-world study

Variate Classification Regression coefficient Standard error P value Odds ratio 95% CI
Maintenance Yes/no  − 0.854 0.238  < 0.0001 0.412 0.22–0.59
Gender Woman/man 0.678 0.678 0.039 1.335 1.08–3.84
Clinical stage IIIb/IV 0.732 0.732 0.065 1.886 0.97–3.06
Age  < 65 / ≥ 65 years 0.398 0.398 0.078 1.248 0.78–1.85
Distant metastasis No/yes 0.232 0.232 0.148 1.325 0.44–2.12
Pathological type Adenocarcinomas/squamous 0.328 0.328 0.237 1.433 0.81–1.97
Smoking history No/yes  − 0.258  − 0.258 0.468 0.680 0.54–2.38
  1. P value was calculated by Cox regression model and odds ratio was showed as the ratio of risk of death between the two classifications in each variate
