Diagnostic values of variables for discriminating axSpA of the active group from the inactive group.

	AUC	95% CI	Optimal cutoff point	Specificity	Sensitivity
CAR	0.701	0.638-0.758	0.3644	79.0%	58.5%
NLR	0.550	0.485-0.614	1.46	85.8%	27.7%
PLR	0.528	0.463-0.592	127.385	42.6%	69.2%
MLR	0.532	0.466-0.596	0.245	54.0%	60.0%
ESR	0.685	0.622-0.743	15.5	52.3%	76.9%
CRP	0.691	0.629-0.749	10.85	71.6%	63.1%

CAR: C-reactive protein to albumin ratio; NLR: neutrophil-lymphocyte ratio; PLR: platelet-lymphocyte ratio; MLR: monocyte-lymphocyte ratio; CRP: C-reactive protein; ESR: erythrocyte sedimentation rate; AUC: areas under the ROC curve; 95% CI: 95% confidence interval.
