Sorry I had too many tabs open in my browser and it crashed, I lost the tab and could not recover. It was an archived report and was a full report showing test method etc. It started with 30 participants, but one was excluded after the first week for non compliance of the diet.
It was not the original 2011 report, that only had 11 subjects. It is not the latest 2017 report either, but an interim one. I think this press release refers to it, but i cannot find the copy report I was reading just now.

I see the 2017 report was published by a different dept - Magnetic Resonance Centre, so this may be the one you were talking about. I think this study has yet to report any findings as it appears to still be in progress.
Edit to add here is the summary published 2016

Prof Taylor has done 2 studies so far Counterpoint 2011 and Counterbalance 2016 (I'm guessing those are publication dates) at least that's what he told me when I asked.
They are currently doing DiRECT which is the new one with over 300 participants which has been running for one year. Results should be published soon.
