Responder Threshold for Patient-Oriented Eczema Measure (POEM) and Children’s Dermatology Life Quality Index (CDLQI) in Adolescents with Atopic Dermatitis
Bibliographic record
Abstract
INTRODUCTION: The Patient-Oriented Eczema Measure (POEM) assesses patient-reported frequency of atopic dermatitis (AD) symptoms, while the Children's Dermatology Life Quality Index (CDLQI) measures the impact of skin disease on health-related quality of life (HRQoL) in children. There is currently no threshold for clinically meaningful within-person change in POEM or CDLQI scores in adolescents. Here we empirically derive within-person thresholds of meaningful within-person change in POEM and CDLQI scores in adolescents with moderate-to-severe AD. METHODS: Data were used from a phase 3, randomized, double-blind, placebo-controlled trial of dupilumab in adolescents (aged ≥ 12 to < 18 years) with moderate-to-severe AD. Anchor-based methods were employed using the mean change in POEM and CDLQI scores from baseline to week 16 linked with a 1-point improvement in Patient Global Assessment of Disease (PGAD), a score of "a little better" on the Patient Global Assessment of Treatment effect (PGAT), a 50-74% improvement from baseline in the Eczema Area and Severity Index (EASI-50-74), and a 1-point improvement in Investigator's Global Assessment (IGA) score. RESULTS: A mean change of - 7.8 and - 5.6 in the POEM score was associated with PGAD and PGAT anchors, respectively. EASI-50-74 was associated with a mean change in POEM score of - 8.2, while the IGA anchor was associated with a mean change of - 7.9 in POEM score. The mean changes in CDLQI score associated with PGAD and PGAT anchors were - 6.4 and - 6.6, respectively, while CDLQI mean scores changed by - 8.3 and - 8.0 for the EASI and IGA anchors, respectively. CONCLUSION: In adolescents (aged ≥ 12 to < 18 years) with moderate-to-severe AD, a within-person change of 6-8 points in POEM and CDLQI scores, independently, can be considered a reasonable responder threshold for clinically meaningful change in each of the two scales, respectively.

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.
