Inflammation-based prognostic scores

Scoring system Score
Neutrophillymphocyte ratio (NLR)
Neutrophil count: lymphocyte count ≥ 5 1
Neutrophil count: lymphocyte count < 5 0
Derived neutrophillymphocyte ratio (dNLR)
Neutrophil count: (leucocyte count–neutrophil count) ≥ 3 1
Neutrophil count: (leucocyte count–neutrophil count) < 3 0
Lymphocytemonocyte ratio (LMR)

Lymphocyte count: monocyte count ≥ 2.35 0
Plateletlymphocyte ratio (PLR)
Platelet count: lymphocyte count > 300 2
Platelet count: lymphocyte count 150–300 1
