Research Design and Analysis Book

I have personal experience with kidney failure.and I'm also a doctor! but I did not choose a specialization yet.The pain which I suffer are increasing day by day.There is no chance for a kidney transplant.This book is very important for me.I understand many things about the history of renal failure. WE Studied at the university some of these things, but from standpoint of therapeutic and functional. I've gained some therapeutic ideas after reading this book,and I plan to transfer to the paper by theory.This is not a book for doctors and medical students only.It is a book for anyone with a personal experience or one of his friends with Renal Failure..
