Patient laboratory data over time.

Age (years)	36.96	37.01	41.24	41.43	43.20	43.27	43.29	43.35
HbA1C (%)		5.7	6.7	6.3		6.2
FBG (mg/dL)	123	113			131	198	115	188
C-peptide (ng/mL)								7.0
Fasting Insulin (mcU/mL)							14.7
Glucose, 2 hr Post 75 gm Oral Glucose Load							178
Total Cholesterol (mg/dL)	213	250	215	154	153
HDL	52	47	37	39	38
TG	277	342	397	165	144
LDL	106	142	107	81	88
BMI (kg/m^2)		25.1	25.6	24.4		24.8

HbA1C = hemoglobin A1C; FBG = fasting blood glucose; HDL = high density lipoprotein cholesterol; TG = triglyceride; LDL = low density lipoprotein cholesterol; BMI = body mass index; normal reference ranges for laboratory: (1) insulin (mcU/mL): (2.6–24.9); (2) C-peptide (ng/mL): (1.1–4.4). Note. For the duration listed, the patient was taking a moderate-intensity statin and not taking any medication for treatment of diabetes.
