Personally, I have stopped reading about drug. Why, well simply the scientific and medical communities seem so divided on the results so far. Questions are still being raised in debate for and against. I am part of neither of those communities, so it makes it hard for an ordinary person like me to decide. Hopefully, my doctor doesn’t have to choose.
There is one exception. I will be interested in seeing the results of an announced Oxford University study (https://www.bbc.com/news/health-57570377). If you click on the link https://secure.phc.ox.ac.uk/sentry/national111/live/survey/open?id=screening&path=dept it will take you to a sign up page. On there you can download the PRINCIPLE Participant Information Leaflet which explains the test in detail.
It is mentioned that it is the gold standard for such testing and hopefully it can give everyone some clear answers. In the meantime, I am sure Doctors will proscribe what they feel at the time is their best choice from the options available for treatment, even if sometimes they may feel under severe emotional pressure to do differently or achieve better results.
