Abstract

fetched live from OpenAlex

Importance: Defining on-treatment remission in plaque psoriasis is important for benchmarking patient responses to therapies. This also helps to facilitate shared understanding, align treatment expectations, and enable more effective psoriasis management. Objective: To establish a consensus-based definition of on-treatment remission for plaque psoriasis through a multistage Delphi initiative. Evidence Review: The Remission Workgroup from the medical board and scientific advisory board of the National Psoriasis Foundation engaged various stakeholders, both US based and international, to participate in the consensus process. Following a working group meeting to determine the overall consensus approach, a systematic review of remission definitions in the current literature was performed. This review helped to inform the content of consensus materials. The consensus effort involved 2 stages: pre-Delphi interviews and surveys to inform the Delphi questions, followed by a Delphi exercise with physicians to define on-treatment remission for plaque psoriasis. Outcome measures considered included body surface area (BSA), Investigator Global Assessment (IGA), the product of the Physician Global Assessment and body surface area (PGA × BSA), and Psoriasis Area and Severity Index (PASI) score at various cutoff levels and time points. Findings: The consensus process involved 92 stakeholders, including dermatologists, rheumatologists, researchers, patients, payers, and life sciences professionals. In the pre-Delphi interviews and surveys, patients emphasized that on-treatment remission meant the absence of psoriasis signs and symptoms while recieving therapy. Payers expressed that defining remission is important for long-term treatment coverage. Following the Delphi exercise and discussion with participating physicians specializing in psoriatic disease management, on-treatment remission in plaque psoriasis was defined as patients maintaining a BSA of 0% or IGA of 0 for at least 6 months while on treatment. Conclusions and Relevance: Through a Delphi consensus process, on-treatment remission for plaque psoriasis was defined as patients maintaining a BSA involvement of 0% or IGA of 0 for at least 6 months while on treatment. This clear and standardized benchmark is applicable to both research and practice settings.

Not 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.
