Fig 4. Overall survival in Study 1108 at different cutoffs for PD-L1 expression in tumor cells (TC) or tumor-infiltrating immune cells (IC) with cutoffs of ≥ 1%/≥ 1% (A), ≥ 10%/≥ 25% (B), ≥ 25%/≥ 25% (C), and ≥ 50%/≥ 25% (D).

CI, confidence interval; IC, tumor-infiltrating immune cell; HR, hazard ratio; NA, not applicable; OS, overall survival; PD-L1, programmed death ligand-1; TC, tumor cell.
