Development and evaluation of a Global Acne Severity Scale (GEA Scale) suitable for France and Europe: Global Acne Assessment Scale
Abstract
BACKGROUND AND OBJECTIVE: Many acne grading methods exist; however, there is no agreed-upon standard. Our objective was to create and validate a reproducible acne assessment scale for rating the severity of juvenile facial acne suitable for use in France and Europe. METHODS: The scale we created described the different types of acne lesions in a manner similar to global assessment scales used in clinical trials. The scale was then validated by seven expert dermatologists in the field of acne [the Global Evaluation Acne (GEA) group] first on 34 photographic cases of Caucasian acne patients and second by clinical examination of 22 acne patients. RESULTS: There was good agreement in Investigators' assessments of acne both on photographs and patients (R = 0.8057; P < 0.0001, and R = 0.8437; P = 0.0015). CONCLUSION: The GEA Scale is a global scale validated both on photographs and acne patients which can be used either in clinical research or by the dermatologist in his office.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
