Bibliographic record
Abstract
Objective Evaluate patient‐reported outcomes after 6 months of on‐label guselkumab use in patients with rheumatologist‐diagnosed active psoriatic arthritis (PsA) enrolled in the CorEvitas PsA/Spondyloarthritis Registry. Methods This analysis includes registry participants who initiated and persisted with on‐label guselkumab (after US Food and Drug Administration approval for PsA; 100 mg at weeks 0, 4, and every 8 weeks) at their 6‐month follow‐up visit (On‐Label Persisters). Among patients not meeting response criteria at baseline, responses at 6 months were determined for patient‐reported outcomes, including patient‐reported pain (0–100 mm visual analog scale), patient global assessment of arthritis + psoriasis (PtGA; 0–100 visual analog scale), and Health Assessment Questionnaire‐Disability Index (HAQ‐DI; 0‐3). Unadjusted, nominal P values were calculated via single‐proportion, one‐sided test (H 0 = 0%; α = 0.05). Results Of 90 On‐Label Persisters, most had treatment‐resistant PsA (92.2% and 73.3% previously received ≥1 and ≥2 biologic/targeted synthetic disease‐modifying antirheumatic drugs, respectively), with mean (SD) baseline patient‐reported pain, PtGA, and HAQ‐DI scores of 57.0 (24.6), 50.3 (24.4), and 0.9 (0.6), respectively. Among those with patient‐reported pain and PtGA scores of at least 15 at baseline, 40.2% (33/82) and 46.8% (36/77), respectively, achieved at least 15‐mm reductions at 6 months; among those with HAQ‐DI scores of at least 0.35 and more than 0.5 at baseline, respectively, 30.4% (21/69) achieved improvements of at least 0.35 and 10.3% (6/58) achieved scores of 0.5 or lower at 6 months (all nominal P < 0.001). Conclusion Pain and physical function are important contributors to health‐related quality of life. In this real‐world population of patients with treatment‐resistant PsA and 6 months of persistent guselkumab treatment, clinically meaningful improvements in pain and physical function were achieved by approximately 40% and 30% of patients, respectively.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
