FPG, fasting plasma glucose; HOMA-IR, homeostatic model assessment of insulin resistance.

* Significant difference between baseline and week 4 data (P < 0·05).

† Significant difference between test and control data (P < 0·05).

‡ Significant tendency between test and control data (P < 0·1).

§ To convert glucose from mg/dl to mmol/l, multiply by 0·0555.

ǁ To convert TAG from mg/dl to mmol/l, multiply by 0·0113.
