Cryptographic Attestation
When this article was published, a named physician, Dr. Jacob Egbert, D.O., reviewed and approved the medical content. Authoritize then sealed it: its exact wording was run through SHA-256 to produce a unique fingerprint (the content hash). Change a single character of the article and that fingerprint changes completely.
That fingerprint was then locked into an append-only chain: each article's record carries the fingerprint of the one before it, so the whole publishing history is tamper-evident. Silently editing an older article would break every link that came after it.
Finally, an independent timestamp authority co-signed when the fingerprint existed, so the date can't be backdated. Your browser just recomputed the chain link from the values below to confirm this record is internally consistent, no need to take our word for it.
Dr. Jacob Egbert, D.O. is responsible for the medical accuracy of this article. Authoritize provides the cryptographic seal, the chain, and the independent timestamp. It verifies that the content has not changed since the physician approved it. It does not author or endorse the clinical content.

Your browser computed SHA-256(previous record + content hash) and got 2c58602ac2a3…, matching the chain hash on record.
This article links to the one published before it, forming an unbroken chain.
An RFC 3161 trusted timestamp was issued by http://timestamp.digicert.com. This token independently proves the content hash existed at the time embedded inside it, and it cannot be backdated.
