Change in Baseline to Last Observation In Normalized Insulin Sensitivity Index at Low Insulin Phase Using Change in Weight as a Covariate

Normalized insulin sensitivity index (Mffm/I) was defined as the ratio of whole body glucose disposal rate normalized to fat-free mass (Mffm) divided by the plasma insulin concentration (I) during steady-state conditions of the clamp procedure. Units:\[(mg glucose)\*min\*mL\] / \[(kg fat free body mass)\*(micro IU insulin)\]

Time frame: baseline and 12 weeks

Population: N=number of patients with a baseline and post-baseline result within each treatment group for Mffm/I and weight.
