Influence on overall MARD of different signal processing of day 1 data to correct for bias and lag.

Signal Processing	Symbol	MARD (%)	MAD (mmol/L)	PEG zone A/A+B (%)
None (raw FGM scans vs SMBG)	$y_{F G M}$	12.3	1.0	81.7/100
Bias corrected, multipoint	$y_{F G M, B c o r r}$	9.2	0.8	91.2/100
Bias corrected, 1-point	$y_{F G M, B c o r r 1 p}$	11.4	0.9	83.0/100
Bias corrected, 2-point	$y_{F G M, B c o r r 2 p}$	9.7	0.7	87.7/100
Bias and lag corrected, multipoint	$y_{F G M, B L c o r r}$	6.6	0.5	97/100
Only lag corrected, multipoint	$y_{F G M, L c o r r}$	11.7	0.9	81.5/100
Only smoothed, multipoint	$y_{F G M, s m o o t h e d}$	11.9	1.0	82.2/100
