Time to definitive 10-point deterioration in physical and role functioning on the EORTC QLQ-C30 questionnaire
The EORTC QLQ-C30 is a questionnaire developed to assess the health-related quality of life of cancer participants. It assesses 15 domains consisting of 5 functional domains (physical, role, emotional, cognitive, social) and 9 symptom domains (fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea, financial difficulties) and a global health status/quality of life (QoL) scale. All of the domain scores range from 0 to 100. A high score for a functional scale indicates a high and healthy level of functioning but a high score for a symptom scale indicates a high level of symptoms.
The time to definitive 10 point deterioration of physical functioning and role functioning is defined as the time from the date of randomization to first onset of ≥10 points increase from baseline (worsening) of the corresponding scale score, with no later change below this threshold or death due to any cause.
Time to definitive 10-point deterioration in symptom scores for chest pain, cough and dyspnea on the EORTC QLQ-LC13 questionnaire
The Lung Cancer module of the EORTC's quality of life questionnaire (EORTC QLQ-LC13) is used in conjunction with the EORTC QLQ-C30 and provides information on an additional 13 items specifically related to lung cancer. The lung cancer module incorporates one multi-item scale to assess dyspnea, and 9 single items assessing pain, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis. All of the domain scores range from 0 to 100. A high score indicates a high level of symptoms.
The time to first 10 point deterioration symptom scores of chest pain, cough and dyspnea is defined as the time from the date of randomization to first onset of ≥10 points increase from baseline (worsening) of the corresponding scale score, with no later change below this threshold or death due to any cause.

Utility scores of the EQ-5D-5L
EQ-5D-5L is a standardized participant completed questionnaire that measures health-related quality of life and translates that score into an index value or utility score. EQ-5D-5L consists of two components: a health state profile and an optional visual analogue scale (VAS). EQ-5D health state profile is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: 1= no problems, 2= slight problems, 3= moderate problems, 4= severe problems, and 5= extreme problems. Higher scores indicated greater levels of problems across each of the five dimensions.

Time from date of randomization to the first documented progression on next line therapy or death from any cause, whichever occurs first
Time to definitive deterioration of the ECOG performance status
Time to definitive deterioration of the ECOG PS by one category of the score. The ECOG PS is a measure of functional status. It ranges from 0 to 5, with 0 denoting perfect health and 5 death. A deterioration is considered definitive if no improvements in the ECOG PS status is observed at any subsequent time of measurement during the treatment period following the time point where the deterioration is observed.
