Hi Carol, Sorry, I don’t know as yet!  The endocrinologist involved in this paper said the UK study showed little evidence of cardio problems and that it was only mentioned as it was raised by NIH.  Their study will be referenced in the full paper and once I have a copy of the UK paper I will send it to you too and will ask more questions.  I think we may have to try and get hold of the NIH study paper too!
