TABLE II. Iron parameters, CD4 cells and viral load correlations of antiretroviral naïve Brazilian men living with human immunodeficiency virus (HIV).

Variables	CD4 cells				Viral load (HIV RNA copy/mL)
	Univariate		Multivariate		Univariate		Multivariate
	eB (CI-95%)	p value	eB (CI-95%)	p value	eB (CI-95%)	p value	eB (CI-95%)	p value
Iron intake (FFQ) (n = 51)	0.98 (0.96-1)	0.11	0.99 (0.97-1.01)	0.2	1.15 (1.04-1.31)	< 0.01	1.12 (1.02-1.25)	< 0.01
Iron intake (3dFR) (n = 34)	0.99 (0.97-1.01)	0.22	0.99 (0.97-1.01)	0.29	1.1 (1.02-1.2)	0.01	1.09 (1-1.2)	0.02
Serum iron (n = 51)	1.01 (1-1.01)	< 0.01	1.01 (1-1.01)	<0.01	0.98 (0.97-1)	0.01	0.98 (0.97-1)	0.01

CI-95%: confidence interval 95%; eB: effect of the variables in the CD4 cells numbers or in viral load; FFQ: food frequency questionnaire; 3dFR: 3-day food record. The multivariate analysis was performed to adjust the analysis considering the time of HIV infection.
