<qa>  What is the name of the study design that allows a cross-sectional perspective?The study design allows a cross-sectional perspective with collection of detailed patient and clinical characteristics at enrollment followed by longitudinal assessment of clinician and patient-reported endpoints every three months. Centralized follow-up will be conducted by having sites upload patient data following each visit via the web-based data system, with patients who do not show up for site visits being contacted via telephone by the Duke Clinical Research Institute DCRI call center. Site recruitment and patient enrollment will be weighted based upon provider specialty and ability to enroll patients with NSCLC with the specified inclusion criteria.
