Kaplan–Meier curves for PFS, stratified by PDL1 level. Patients were divided into three subgroups based on their measured PDL1 level (low: “<1%”, medium: “1–49%”, high: “≥50%”). In the low PDL1 group, the median PFS was 11 months; in the medium PDL1 group, the median PFS was 11 months; in the high PDL1 group, the median PFS was 16 months. The p-value of the multivariate log-rank statistic for PFS difference between the three groups was 0.01. In a Cox proportional hazards (PH) model with terms for PDL1 level, the low PDL1 level was associated with a hazard ratio (HR) of 1.85 (95% CI [1.23, 2.77], p = 0.003) compared to the high PDL1 level; the medium PDL1 level was associated with an HR of 1.79 (95% CI [1.15, 2.78], p = 0.01) compared to the high PDL1 level.
