Multiple linear regression models to determine the relationships between demographic indices, circulating leukocyte populations, and renal function in study subjects with No CKD + CKD 1-5.

Model	Cohort	Number	Response variable	Explanatory variable	Coefficient	95% CI	†P
1a	No CKD + CKD 1-5	187	eGFR	Constant	110.22	94.22, 126.21	< 0.001
				Age (years)	−26.01	−31.84, −20.17	< 0.001
				Gender (M)	2.55	−9.14, −0.98	0.46
				#Monocyte	−5.27	−9.47, −1.06	0.015
