Representative flow dot plots of monocyte gating strategy and the percentage of programmed cell death receptor ligand-1 (PD-L1) on monocytes in different groups. The monocytes (gate B) were gated in the dot plots of side-scatter characteristics (SS) vs CD14. The multiple dot plots of CD14 vs PD-L1 are representative of the percentage of monocytes in healthy control, survivor, and nonsurvivor groups
