I am a newcomers. what are the efficacy, safety and derived variable. what are the safety and efficacy parameters taken if disease is taken as diabetes and alzheimer's disease. I have searched in the internet but till now not getting exact one. plz help.
That isn't really a SAS question. Rather it is more for the clinical people on the trial. You can get some ideas of the intellectual content for efficacy and safety by going to clinicaltrials.gov and looking at the postings for the different diabetes and Alzheimer's drugs. You could also get an idea by looking at the clinical research papers for trials on those topics.
