Area under the curve calcuation

NoNoNoNoNoNo — Mon, 22 Jan 2018 19:32:05 GMT

Hello, I am very new to SAS Studio. I have just completed data collection on my thesis and have to perform an area under the curve analysis on blood glucose concentrations. For my data, I have 13 participants, who completed 4 different sessions, and we took 7 blood samples per session. I need to take the glucose concentrations from the blood samples, and convert this to area under the curve, and then perform ANOVA on these concentrations to determine if there were any sig differences between each treatment.

I have used SPSS and GraphPad before, but my supervisor wants me to learn SAS. In the past, AUC was a simple selection on a screen, but I'm having a lot of difficulty finding where it is in SAS Studio. Any help at all would be greatly appreciated!
