Table 2

Effect of metformin with placebo 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	160.75±2.60	155.33±2.31	<0.05
PPBG	218.51±3.53	211.57±2.88	<0.05
HbA1c	8.18±0.12	8.01±0.11	>0.05
Plasma AA	0.24±0.006	0.27±0.01	>0.05

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.
