PD was defined as at least a 20% increase in the sum of diameters (SOD) of target lesions, taking as reference the smallest SOD at prior timepoints, including baseline. In addition to the relative increase of 20%, the SOD must also demonstrate an absolute increase of at least 5 millimeters (mm). Kaplan-Meier (K-M) method was used to estimate median PFS. 95% CI for median was computed using the method of Brookmeyer and Crowley.","dispersionType":"95% Confidence Interval","groups":[{"description":"Participants received platinum-containing anticancer treatment regimens (with or without pembrolizumab) at the study center as chosen by the treating investigator based on NSCLC histology.
