Jen is reviewing information about a new treatment for arthritis pain that she saw on an informational website. Most of the information is testimonials from satisfied users.Which best indicates that this information is unreliable?

Testimonials describe individual experiences, so they are anecdotal evidence. They do not establish that the treatment works for arthritis pain or rule out other explanations; stronger evidence would come from well-designed studies. Therefore, claims based mostly on anecdotal evidence are the best indication that the information is unreliable.
