Comparison of red blood cell parameters in study participants, stratified according to the level of UA.

	Low UA ()	Normal UA ()	High UA ()	value	value
Age (years)				7.201	<0.001^a,b
BMI (kg/m^2)				0.458	0.632
MCH (pg)				3.199	0.041^a,b
MCHC (g/l)				18.965	<0.001^b,c
MCV (fl)				13.665	<0.001^a,b,c
RDW (%)				5.168	<0.001^c
RBC (10^12/l)				114.456	<0.001^a,b,c
Hemoglobin (g/l)				102.371	<0.001^a,b,c
UA (mmol/l)				6004.230	<0.001^a,b,c
Cr (mmol/l)				206.204	<0.001^b,c
UA/Cr ratio				2106.472	<0.001^a,b,c

RDW: red blood cell distribution width; MCH: mean corpuscular hemoglobin; MCHC: mean corpuscular hemoglobin concentration; MCV: mean corpuscular volume; RBC: red blood cell count; Cr: creatinine; UA: uric acid; BMI: body mass index. Low UA: male ( mmol/l), female ( mmol/l); normal UA: male ( mmol/l), female ( mmol/l); high UA: male ( mmol/l), female ( mmol/l). ^a for the difference between low and normal (1-way ANOVA with the LSD post hoc test). ^b for the difference between low and high (1-way ANOVA with the LSD post hoc test). ^c for the difference between normal and high (1-way ANOVA with the LSD post hoc test).
