Metric

Calculation

PNI

Prognostic nutritional index. 10 × serum albumin level (g/dL) + 0.005 × total lymphocyte count (per mm3)

AAPR

Albumin (ALB): alkaline phosphatase (ALP)

WLR

White blood cell (WBC) count: lymphocyte count

LMR

Lymphocyte count: monocyte count

NLR

Neutrophil count: lymphocyte count

PLR

Platelet count: lymphocyte count

PPR

Platelet distribution width: platelet count

MPR

Mean platelet volume (MPV): platelet count

SII

Systemic immune-inflammation index. Platelet count × neutrophil count/lymphocyte count

dNLR

Derived (d) NLR: neutrophil count/ (WBC − lymphocyte count)

PIR

Prothrombin time (PT): international normalised ratio (INR)

FFR

Fibrinogen degradation product (FDP): fibrinogen (FIB)

DFR
