Hi Sasi!

❝ ... i need to calculate AUC0-72 instead of AUClast and AUCinf how can i calculate this value by using winnonlin.

I'm not sure whether I understand your question.

• If your study was planned to be evaluated with AUC_0-72 as the primary target parameter, I would expect that your last sampling time point was 72 hours - therefore AUC_0-72 = AUC_last.
  
• If you have sampled for a longer time period and later on changed your mind (why?), you have to exclude these time points from calculations:
  Assuming your sampling times are contained in a column named 'time' > click this column once > Data > Exclude > Criteria >
  Write '72' in the field 'Find'
  In the 'Search Area' select the second option 'Column: time'
  In the 'Operation' field select '>'
  Check [x] the box 'Exclude Row Matching Criteria'
  Click 'Exclude'
  Then proceed as usual in th BE-wiz.
