*Missing data in refractory group.
†Missing data in response group.
LDH = lactate dehydrogenase; PNN = polynuclear neutrophils; PNEo = polynuclear eosinophils; PNBaso = polynuclear basophils; CRP = C-reactive protein.
Data are distribution of biologic biomarkers in refractory and responding patients at baseline (BL) and change 3 mo after anti-PD1 initiation (Δ3, expressed as a percentage). Wilcoxon test did not show significant mean differences between those 2 groups.
