Multivariate analysis for independent risk factors of thoracic OLF.
VariablesOR (95% CI)
Age (year) (≥60 versus <60)2.14 (0.67-6.85)0.20
BMI (kg/m2) (≥25 versus <25)9.17 (3.22-26.08)<0.01
NLR (≥2.42 versus <2.42)1.58 (0.45-5.58)0.48
SII (≥621 versus <621)12.16 (2.95-50.17)<0.01
OLF: ossification of the ligamentum flavum; OR: odds ratio; CI: confidence interval; BMI: body mass index; NLR: neutrophil-to-lymphocyte ratio; PLR: platelet-to-lymphocyte ratio; MLR: monocyte-to-lymphocyte ratio; SII: systemic immune inflammation index. Variables with were considered as independent risk factors.
