Agreement on Symptoms Between Children With Ulcerative Colitis and Their Caregivers
Bibliographic record
Abstract
ABSTRACT: As part of the development of the TUMMY-UC, a patient-reported outcome (PRO) measure for pediatric ulcerative colitis (UC), we aimed to explore agreement on UC symptoms between children and their caregivers. We conducted 44 interviews with children ages 8-12 years, who completed the PRO version of the TUMMY-UC, and their caregivers, who completed the observer-reported outcome (obsRO) version. There was excellent agreement between the total TUMMY-UC PRO and obsRO scores (intra-class correlation coefficient = 0.92 [95% confidence interval 0.74-0.98]). The obsRO scores were always within the same disease-activity category as the corresponding PRO score (ie, remission, mild and moderate-severe disease). There was a strong correlation of the TUMMY-UC PRO and obsRO scores with physician global assessment of disease activity (r = 0.94 and r = 0.90, respectively, P < 0.001) and the pediatric UC activity index (r = 0.95 and r = 0.96; P < 0.001). These data support conceptual equivalence between the PRO and obsRO TUMMY-UC versions, and provide support for their incorporation into one score.

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.
