Correlations of true and reported total sugars intake and total sugars density on log scale, and AFs for reported total sugars intake and total sugars density on log scale from a ME model for the urinary sugars biomarker^*

		Men (n = 261)		Women (n = 223)
	Instrument	Attenuation Factor (AF)	Correlation with true intake	Attenuation Factor (AF)	Correlation with true intake
Total sugars intake (g/day)	FFQ	0.283 (0.058†)	0.431 (0.069)	0.169 (0.068)	0.163 (0.064)
	Single 24HDR	0.304 (0.056)	0.499 (0.067)	0.196 (0.069)	0.206 (0.070)
	Avg. of two 24HDR	0.407 (0.074)	0.577 (0.076)	0.291 (0.102)	0.252 (0.085)
Total sugars density (g/1000 kcal)	FFQ	0.385 (0.093)	0.500 (0.090)	0.331 (0.129)	0.231 (0.087)
