I really cannot understand why you think it was important for the sentence to be that way - I was not resisting you.  I asked for sources, and you provided them.  I have made the change you suggested, and added the NEJM reference.  Hopefully, that will help prevent it from being reverted.  Sorry I did not pay attention to the fact that you're not yet able to be bold - it was not meant to add to your frustration.  Nice suggestion, and I'm glad you were persistent.
