Subject   st: Calculating area under the curve for insulin

Hello,
I am trying to use STATA to calculate the area under the curve for
insulin levels measured during an oral glucose tolerance test.  So, I
have insulin (and glucose) levels at time points 0, 30, 60, 90, 120,
180, for 62 patients.  For each pt, I specifically want to calculate the
AUC for insulin, and additionally need to subtract out the baseline
insulin level.  Does anyone know how to do this?
 
Thank you,
