Are postoperative NLR and PLR associated with the magnitude of surgery-related trauma in young and middle-aged patients with bicondylar tibial plateau fractures? A retrospective study

Table 3 Multivariable logistic regression analyses of variables associated with the magnitude of surgery-related trauma

Variable	Multivariate analysis		P
Variable	OR	95 % CI	P
Length of incision (> 19.0 cm)	14.71	4.03–52.63	< 0.001

Postoperative 1st day PLR (> 223.9)	4.24	1.20-14.93	0.025
Postoperative 1st day NLR (> 10.1)	1.30	0.36–4.69	0.691
Postoperative 1st day RBC (< lower limit × 10^12/L)	1.19	0.20–7.02	0.846

Hypertension (yes)	1.28	0.24–6.85	0.776
Diabetes (yes)	1.38	0.12–16.13	0.804
Anesthetization (general)	2.74	0.83–9.02	0.097

Note: P value < 0.05 was considered statistically significant. Abnormal reference range for RBC: male < 4 × 10^12/L and female < 3.5 × 10^12/L, for HGB: male < 130 g/L and female < 115 g/L. Abbreviations: BMI, body mass index; NLR, neutrophil-to-lymphocyte ratio; PLR, platelet-to-lymphocyte ratio; RBC, red blood cell; HGB, hemoglobin; HCRP, hypersensitive C-reactive protein
