A Comprehensive Assessment Tool for Psoriasis — An Unmet Need: Report from the GRAPPA 2014 Annual Meeting
Bibliographic record
Abstract
Psoriasis is a chronic inflammatory skin condition that has several distinct clinical subtypes, the most common of which is plaque psoriasis. Other non-plaque subtypes, however, including scalp, nail, inverse, and palmoplantar, have been demonstrated to be more common than previously believed, are associated with a significant burden of disease, and are likely underdiagnosed and undertreated. Understanding the effects of these non-plaque psoriasis subtypes can be challenging given that the gold standard psoriasis tool, the Psoriasis Area and Severity Index, is mostly directed at plaque psoriasis. Therefore, a tool that can more comprehensively assess the psoriasis patient represents an unmet need in dermatology. Herein we discuss the concept of an ideal tool that addresses both plaque and non-plaque subtypes, with equal contribution from physician and patient, as discussed at the 2014 Annual Meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
