The above source is a petition to the FDA; certainly wouldn't hurt to review it, and see if any additional updates are available.
Admin note added later. A petition to the FDA is just that- a petition. It is not fact, it is not the FDA's position, and it does not include any rebuttal, acceptance, or refusal of acceptance of the information by the FDA. As a stand alone document is has little value except to say that some individual ( no credentials required) took the time to petition the FDA with this document. While many of these come from responsible researchers, some from clinicians not directly connected to the research, or from the same area of expertise, some also come from the public. Giving the same weight to all would be erroneous.
