EpistemisGOLD Classification of COPD: Spirometric Grade and ABE Group
Since the 2023 review, there are three groups, not four: the old group C disappeared and every exacerbator patient moves to group E, regardless of how many symptoms they have. The numerical degree (1 to 4) and the letter are different axes that do not mix.

This page explains the score but does not run it. In Epistemis, the calculator validates units, flags values outside physiological ranges, and provides the interpretation that a number alone cannot convey.
Epistemis is educational review material. It is not a medical device, does not diagnose or prescribe treatment, and does not replace formal medical training, current clinical guidelines, or professional clinical judgment.
