Uric Acid Provides Protective Role in Red Blood Cells by Antioxidant Defense: A Hypothetical Analysis

Table 4

Multiple linear regressions for associations between UA levels and red blood cell parameters in subjects.

	UA			UA/Cr ratio
		(95% CI)			(95% CI)
Gender	0.306	<0.001 (-0.060 to -0.052)	Gender	0.107	<0.001 (0.217 to 0.336)
Age	0.032	<0.001 (0.000 to 0.001)	Age	0.092	<0.001 (0.006 to 0.009)
RBC	0.245	<0.001 (0.003 to 0.092)	RBC	0.089	<0.001 (0.136 to 0.350)
Hemoglobin	0.138	<0.001 (0.002 to 0.082)	Hemoglobin	0.085	<0.001 (0.004 to 0.011)

RBC: red blood cell count; Cr: creatinine; UA: uric acid.
