I do not agree with this statement of the book. I do not think medical device companies “lack transparency and proper clinical trials”. None of the medical devices will be in the market if they were not good. The FDA does a very through job ensuring everything is proper and is safe for the consumer to use. Maybe the book is talking about something else or a different point of view. But on the information that is posted, it is making the FDA look like they are not doing their job which is not correct. More information on the book should be posted.
