Ann: Recruitment Completed in Prospective Sleep Apnoea Study, page-50

If you want to wait a few weeks, you can ask him yourself at the AGM.
I have read it in posts in the begining of the company's listing. A bloke "tag" wiseone, has all info if you want to ask him, or if Redbar is reading this perhaps he might offer some info. But I found out by researching the web, announcements and annual reports.
The answer you seek is in the detail of the early posts. I'm sorry if i cant be of any further assistance.
