∗Multivariate-adjusted odds ratio adjusted by age, male gender, smoker, peripheral white blood cell count, peripheral monocyte blood cell count, haemoglobin, eGFR, and hs-CRP.
Statistical significance based on binary logistic regression analysis.
CKD: chronic kidney disease; eGFR: estimated glomerular filtration rate; hs-CRP: high-sensitivity C -reactive protein.
