CRP, C‐reactive protein; WBC, white blood cell.
a
Statistical analysis: Chi‐square test was used to analyze P‐value and ORs. WinPepi Software, Version 10.0 was applied. The AORs with their 95% CIs were calculated after controlling for plasma YKL‐40 and CRP concentrations as well as WBC and neutrophil counts using logistic regression model. SPSS statistical package version 12.0 was applied.
b
Cutoff levels were estimated according to receiver‐operating characteristic curves of these parameters.
