N0: not spread to regional LN; N1: spread to ipsilateral pulmonary or hilar nodes; N2: spread to ipsilateral mediastinal or subcarinal nodes; N3: spread to contralateral mediastinal, hilar, or supraclavicular nodes. M0: no distant metastasis; M1a: malignant pleural or pericardial effusion or pleural or pericardial nodules or separate tumor nodule(s) in a contralateral lobe; M1b: single extrathoracic metastasis; M1c= multiple extrathoracic metastases (1 or \>1 organ).

Higher score indicated worse health status.

PD was defined as cancer worsening based on radiologist's interpretation of the imaging and/or clinician's assessment, and after initiation of first-line dacomitinib treatment. Participants without PD and remained alive (i.e. no date of death) until end of follow-up were censored at the date of last known contact/visit date. Participants lost to follow-up were censored based on the last known contact/visit date. Kaplan-Meier method was used for analysis.
