I'm just popping back to this thread for a moment. I went to an inservice about Evidence Based Nursing the other day. There was some discussion about using discernment with regard to selecting studies and their results. It reminded me of stuff I've learned from Heather/Wyllen. And made me 'think hard' as I reread the first part of this book.
