LDH: Lumbar disc herniation; NEU: Neutrophil ratio; MPV: Mean platelet volume; MON: Mononuclear cell ratio; LYM: Lymphocyte count; RDW: Red blood cell distribution Width; IBIL: Indirect Bilirubin.
ap value was calculated by independent samples t-test. bp value calculated by χ2-test. p < 0.05 indicates statistical significance. The highlighted in bold represent statistical significance.
