Table 3

Effect of metformin with vitamin C on FBG, PPBG, HbA1c and plasma AA in patients with type 2 diabetes mellitus after 12 weeks of treatment.

Parameter	Before treatment	After treatment	𝑃 (paired)
FBG	157.63±3.13	141.18±3.81	<0.01
PPBG	222.24±3.16	206.69±3.31	<0.05
HbA1c	8.26±0.09	7.80±0.08	<0.01
Plasma AA	0.26±0.008	0.45±0.01	<0.001

𝑛=33 in number, FBG: fasting blood glucose, PPBG: postmeal blood glucose, HbA1c: glycosylated hemoglobin, plasma AA: plasma ascorbic acid. FBG, PPBG, and plasma AA are measured in mg/dL.
