Correlation of frequency of programmed death ligand 1 (PD-L1)-expressing neutrophils with inflammatory markers. a The frequency of PD-L1-expressing neutrophils in systemic lupus erythematosus (SLE) patients correlated significantly with erythrocyte sedimentation rate (ESR) (r 2 = 0.32, P <0.0001). b The frequency of PD-L1-expressing neutrophils in SLE patients was not correlated with C-reactive protein (CRP) (r 2 = 0.007, P = 0.4958). c The frequency of PD-L1-expressing neutrophils in SLE patients correlated significantly with immunoglobulin G (IgG) (r 2 = 0.12, P <0.0021). d The frequency of PD-L1-expressing neutrophils in SLE patients was not correlated with Complement 4 (C4) (r 2 = 0.0021, P = 0.6974). e The frequency of PD-L1-expressing neutrophils in SLE patients was not correlated with C3 (r 2 = 0.026, P = 0.1660). f The frequency of PD-L1-expressing neutrophils in SLE patients was correlated negatively with decreased C3 (r 2 = 0.17, P = 0.0094). g The frequency of PD-L1-expressing neutrophils was significantly increased in SLE patients with elevated neutrophil (N) count compared to those with normal N count (P = 0.0372). h The frequency of PD-L1-expressing neutrophils was significantly increased in SLE patients with elevated neutrophil percentages (N%) compared to those with normal N% (P = 0.0437)
