Covariates:
*age, sex, G grade, A grade, hemoglobin level, albumin level, and C-reactive protein
†age, sex, G grade, A grade, hemoglobin level, and C-reactive protein.
Adjusted odds ratios and 95% confidence intervals were analyzed by logistic regression analysis with each of the above factors as covariates.
Abbreviations: AOR, adjusted odds ratio; CI, confidence interval; UA, serum uric acid; Na, serum sodium; K, serum potassium; Cl, serum chloride; Na-Cl, difference between serum sodium and chloride concentrations; cCa, serum corrected calcium; P, serum phosphate.
