Prevalence of anemia after multivariable adjustment among male individuals
Categories for estimated glomerular filtration rate (mL/min/1.73 m2)	Relative risk for anemia	95% confidence interval	P-value
<15	1.68	1.44–1.96	<.001

Differences in estimated glomerular filtration rate among the same estimated glomerular filtration rate category, albuminuria levels, and interaction terms between albuminuria and estimated glomerular filtration rate category were controlled in both models.
