CADLink is a database of evidence extracted from the scientific literature. This literature-based evidence—taken primarily from peer-reviewed publications—is summarized in terms of the cause-effect relationships evaluated in each publication, along with relevant details on study design, location, scale, analytical results, and other parameters. This evidence can then be used to develop and evaluate the causal pathways included in environmental assessments.
CADLink can also be used with CADDIS’ Interactive Conceptual Diagram (ICD) tool, which allows users to develop conceptual model diagrams that depict pathways and link evidence to specific steps in those diagrams.
Access CADLink using the links at the right. Public users can search CADLink and download information; beta testers can search CADLink as well as add new information to the database.
To become a registered CADLink user, visit the EPA Web Application Access page. Request access to the CADDIS community by completing the form, selecting CADDIS from the list under "Select the Community or Application for which you are requesting access," and clicking Submit Registration. Note that the process is slightly different for users with and users without an EPA LAN account, so follow instructions on the web application access page accordingly. You only need to register once! Once you become a member of the CADDIS community, you can log into CADLink (and the ICD tool) at any time.
An updated beta version of CADLink was released on March 6, 2018. Notable improvements include the ability to attach supporting documentation (e.g., spreadsheets, graphics) to CADLink citations; the ability to create term categories; and the ability to create multiple sets of analysis details for a single cause-effect pair. CADLink replaces CADLit, the original CADDIS literature database. CADLit information can still be searched and downloaded via the CADLink interface, but data can no longer be entered into CADLit. We welcome your feedback on potential improvements as we continue development; please contact us with any problems you encounter or to suggest changes.
