Data are expressed as median (interquartile range) or frequency (%).
NGAL, neutrophil gelatinase-associated lipocalin; NGAL/sCr ratio, NGAL-to-serum creatinine ratio; hsCRP, high sensitivity C-reactive protein; cESR, corrected erythrocyte sedimentation rate; NLR, neutrophil-to-lymphocyte ratio; eGFR, estimated glomerular filtration rate; sCr, serum creatinine; BUN, blood urea nitrogen.
