What are the main differences between the former R16 reports and the E-PIC usage reports for ClinicalKey?

The R16 reports were based on COUNTER4 data and will be sunset in April 2026. The R16 Top 20 Content Publications displays only Views; the list of journals and books at the bottom of the report displays Full Text Views, which are comprised of Views and Downloads together.

The ClinicalKey Usage Reports on E-PIC utilize COUNTER5 data which is usage for all content types. These reports also include insight into activities such as Views, Downloads, Prints, Saved Content, Export to Powerpoint, and Email.
