Calculation formula for each index.

Novel SIMs	Computing method
NLR	Neutrophil count (N)/lymphocyte count (L)
PLR	Platelet cell count (P)/lymphocyte count (L)
SII	Neutrophil count (N) $\times$ platelet count (P)/lymphocyte count (L)
SIRI	Neutrophil count (N) $\times$ monocyte count (M)/lymphocyte count (L)
HRR	Hemoglobin (Hb)/red cell distribution width (RDW)

SIMs, systemic inflammatory markers; NLR, neutrophil-to-lymphocyte ratio; PLR, platelet-to-lymphocyte ratio; SII, systemic immune-inflammation index; SIRI, systemic inflammation response index; HRR, hemoglobin-to-red cell distribution width.
