Neutrophil–lymphocyte ratio as a potential marker for differential diagnosis between spinal tuberculosis and pyogenic spinal infection

Table 1 Baseline clinical characteristics of the population

Parameters	STB	PSI	P
Age, years (mean ± SD)	55.70 ± 17.16	63.68 ± 11.52	= 0.001
Gender (male/female)	78:68	34:26	= 0.671
Neutrophil (× 10⁹/L)	6.23 (5.46–7.48)	9.12 (7.52–10.95)	< 0.001
Lymphocyte (× 10⁹/L)	1.60 (1.19–2.01)	0.88 (0.58–1.17)	< 0.001
Monocyte (× 10⁹/L)	0.43 (0.36–0.57)	0.54 (0.39–0.63)	= 0.029
Platelet (× 10⁹/L)	310 (271–347)	248 (234–272)	< 0.001
NLR	3.85 (2.70–5.71)	10.82 (6.79–17.62)	< 0.001
PLR	191.9 (150.6–255.8)	292.9 (213.4–399.5)	< 0.001

Values are shown as the mean, standard deviation, median (IQR), or numbers. Differences between groups were analyzed using Student’s t test or the Mann–Whitney U test for continuous variables and the Chi-square test for categorical variables
