Weight loss was measured by weight lost in kilograms and BMI lost, as well as blood measurements. This trial went for 12 months.
An economic analysis of in terms of a cost-effectiveness analysis will be implemented in this phase. This will involve an estimation of costs associated with both groups (eg., Cost of the Lapband procedure etc)
