(A) Kaplan–Meier plot of progression-free survival comparing the addition of atezolizumab to etoposide and platinum (EP) versus EP alone. The hazard ratio (HR) is 1.33 (95% CI, 0.69-2.56), with a P-value of .35. (B) Kaplan–Meier plot of overall survival comparing the addition of atezolizumab to EP versus EP alone. The HR is 1.13 (95% CI, 0.56-2.28), with a P-value of .72.
