The cumulative incidence of successful weaning rate was higher among the patients harboring EGFR deletion 19 mutation than those with L858R or other uncommon mutations, with a log-rank p value of 0.016 (Figure 2D); it was also higher in the patient without diabetes mellitus (DM) (log-rank p value < 0.001, Figure 2E). This evidence concerns the gene EGFR and diabetes mellitus.
