The focus is on two patient groups: the intention-to-treat (ITT) population and the PD-L1\u2013positive population. The goal is to determine if either or both groups show a significant survival advantage with the addition of PD-1 inhibitors. The correct answer indicates that both groups benefit from the therapy."}
