The CCRAT Gauss Program is an executable that allows the user to project absolute colon cancer risk according to NCI’s Colon Cancer Risk Assessment Tool (CCRAT) algorithm in the batch mode. It also computes 95% confidence intervals for the risk projections. Risk factor data and projection interval ages can be entered for a group of men or women, and corresponding absolute risk projections will be returned. This program may be useful for research purposes when one needs risk projections for an entire study population. The program can be run on either a 32-bit or a 64-bit system.
