Glucometric indices and choice of insulin

Indices	Prefer premixa	Prefer basala
PPGE = PPG − FPG	40–74 mg/dl	< 40 mg/dl
	2.2–4.1 mmol/l	< 2.2 mmol/l
$\text{PFI}=\frac{\text{PPG}-\text{FPG}}{\text{FPG}}$	0.4–0.6	< 0.4
FPG/HbA1cb	≤ 20	≥ 20

FPG fasting plasma glucose, PPG postprandial plasma glucose, PPGE postprandial glucose excursion, PFI prandial fasting index

^aThe cutoff values are arbitrary and are based upon diagnostic values for prediabetes and diabetes. For derivation, refer to Kalra [32]
