This showed that NSCLC patients with EGFR-mutated tumours could be distinguished accurately from those with wild-type EGFR. The area under the curve (AUC) was 0.75 (95% confidence interval (CI) 0.61–0.87; p = 0.0003) for the miR-191 normalised data, and 0.70 (95% CI 0.55–0.82; p = 0.0087) for the miR-16 normalised data. Here, EGFR is linked to neoplasm.
