marginal significancep=0.055
PD-L1 exhibited marginal significance among distinct subtypes (Kruskal-Wallis, p=0.055; figure 1A ) and was still a predictor for PFS (HR: 0.99, 95% CI: 0.98 to 1.00, p=0.005) when adjusting for PTCL subtypes in the multivariate Cox regression algorithm ( figure 1C and online supplemental figure S1B ), indicating the strong and relatively independent predictive capability of PD-L1.
