Table 2. Mean selenium intake (μg/day) assessed with DR and FFQ in 4 areas, and Spearman correlation coefficients.

	DR				FFQ				% Difference
	Mean	±	SD	Median	Mean	±	SD	Median		Crude	Energy-2 adjusted
Men (n=102)	184	±	48	175	132	±	63	116	-28	0.36	0.34
Women (n=113)	146	±	37	142	120	±	72	101	-18	0.32	0.26

¹(FFQ mean - DR mean)/DR mean (%).

²Energy intake was adjusted by residual model.

For n=102, r>0.20 = p<0.05, r>0.26 = p<0.01, r>0.33 = p<0.001.

For n=113, r>0.19 = p<0.05, r>0.25 = p<0.01, r>0.31 = p<0.001.
