	Unadjusted model		Adjusted I model		Adjusted II model		Adjusted III model
	OR (95% CI)	P value	OR (95% CI)	P value	OR (95% CI)	P value	OR (95% CI)	P value
C-reactive protein (mg/L)	1.035 (1.013, 1.058)	< 0.001	1.028 (1.004, 1.052)	0.020	1.044 (1.009, 1.080)	0.012	1.044 (1.006, 1.083)	0.022

Adjust I model adjust for sex and gender; adjust II model adjust for sex, gender, leucocytes, lymphocytes, neutrophils, platelets, and hemoglobin; and adjust III model adjust for sex, gender, leucocytes, lymphocytes, neutrophils, platelets, hemoglobin, sodium ion, and potassium ion
