SECONDARY outcome

Timeframe: Baseline versus 2.4 years

Insulin sensitivity The Matsuda index was calculated as 10,000/square root of (pre-meal glucose x pre-meal insulin x mean 120 min post-meal glucose x mean 120 min post-meal insulin), with higher numbers indicating better the insulin sensitivity.
