Correlations between serum-S1P concentrations and various clinical parameters
| Spearman rho | Significance (P value) | |
|---|---|---|
| PCT | −0.52 | <0.01 |
| IL-6 | −0.39 | <0.01 |
| CRP | −0.28 | <0.01 |
| Creatinine | −0.25 | <0.05 |
| Lactate | −0.24 | <0.05 |
| Fluid balance | −0.23 | <0.05 |
S1P sphingosine-1-phosphate, PCT procalcitonin, IL-6 interleukin-6, CRP C-reactive protein
Correlations between S1P and PCT, IL-6, CRP, creatinine, lactate, and fluid balance were assessed by using the Spearman rank test
