Logistic regression analysis of the association between S1P levels and cerebral collateral circulation (GCC vs. PCC).

	P-value	OR (95% CI)
S1P (ng/mL)	0.014	1.013 (1.003–1.023)
MCP1 (ng/mL)	0.090	0.997 (0.950–1.004)
SBP, mmHg	0.962	0.999 (0.953–1.047)
DBP, mmHg	0.267	0.956 (0.883–1.035)
TC, mmol/L	0.737	0.562 (0.019–16.228)
LDL, mmol/L	0.962	1.115 (0.012–103.57)

GCC, good collateral circulation; PCC, poor collateral circulation; S1P, sphingosine-1-phosphate; MCP-1, monocyte chemoattractant protein-1; SBP, systolic blood pressure; DBP, diastolic blood pressure; TC, total cholesterol; LDL, low-density lipoprotein.
