CHSS Score Explanation:

 

The score is the predicted difference in 5-year survival for a UVR minus a BVR. A positive number favors a BVR; a negative number favors a UVR, with the magnitude of the difference expressed by the number.

 

For example, a CHSS Score of +10 predicts that 5-year survival is 10% greater for a BVR versus a UVR. A score of -20 predicts that 5-year survival after a UVR is 20% greater than after a BVR.
