# Location of Endpoint Quality Control Report

The **quality control report** describes the steps that have been made to ensure the quality of released data. Endpoint quality control report, changelog and corrected\_endpoints file of DF8 can be found [here](https://www.finngen.fi/fi/endpoint-quality-control-data-freeze-8). Changelog for other data freezes can be found [here](https://www.finngen.fi/en/researchers/clinical-endpoints).

**Endpoint quality control** is divided into **two sections**:

* Protocol development that uses old data, but new endpoint definition files and updated Endpointer program
* One that takes place before each release to ensure released data quality. The process has been designed and performed in collaboration between clinical and register teams.
