EGFR and laryngotracheoesophageal cleft: The results of logistic regression analysis showed histologic type (odds ratio [OR] = 12.681, 95% confidence interval [CI] = 4.936–32.578, P < 0.01), sex (OR = 2.168, 95% CI = 1.325–3.545, P = 0.002) and radiologic manifestation of P-LC (OR = 2.966, 95% CI = 1.318–6.672, P = 0.009) to be independent predictors of EGFR mutations, whereas smoking history and EGFR amplification method were not.
