Help > Guideline Comparison
The National Guideline Clearinghouse (NGC) provides you with the ability to generate side-by-side comparisons for any combination of two or more guidelines. A standard set of guideline attributes is included in the Guideline Comparison. Guideline collections are only maintained for the length of your browser session. Once your browser is closed, all guidelines will be removed from your collection.
To construct a Guideline Comparison, you must have generated a Guideline Collection -- a list of guideline titles -- either by using the NGC Search or NGC Browse features.
You can also add single guideline to your Guideline Collection while in a view (e.g., Brief Summary) by clicking on the "Add to Guideline Collection" link on the left-hand navigation bar.
