The agreement
Terms of use
Short, because there is not much to agree to: the public site asks nothing of you and gives you everything it holds.
Last updated
Using the site
Read it, quote it, cite it, check it. No account, no payment and no permission is needed for any of that. If you are writing something that relies on a claim here, link to the record rather than to us in general — the record names its sources and its rung, which is what makes the claim checkable.
Do not scrape the site into a competing database and present it as your own work. The underlying facts are not ours to own and we make no claim to them; the curation, the rubric, the grading and the writing are.
What we do not warrant
We build these records carefully and we publish the method. We do not warrant that they are complete, current or free of error, and the literature they describe changes. Nothing here creates a professional relationship of any kind. See the medical disclaimer, which is the part that actually matters.
To the extent the law allows, we are not liable for what happens when someone acts on information found here. That is the standard sentence, and the honest version of it is the one on the disclaimer page: this is a record, and a record is not a clinician.
When we are wrong
We correct it and say that we did. The rubric carries a revision history, every grade records the phrase it was derived from, and 521 fields are published as explicitly missing. Those three things exist so that an error is findable by a reader rather than only by us.
Links out
Records link to primary sources — journals, registries, regulators. We do not control those and linking is not endorsement; a citation is a pointer to what a source said, which is the point of a citation.
Changes
If these terms change materially, the date at the top of this page changes with them.
