Minimal difference in pain associated with change in quality of life in children with rheumatic disease
Bibliographic record
Abstract
OBJECTIVE: To establish the minimal change on a pain visual analog scale (VAS) associated with change in self-reported quality of life in pediatric rheumatology patients. METHODS: Subjects were a cohort of 533 pediatric rheumatology patients in Toronto. Pain and perceived quality of life were measured at 2 consecutive visits to a clinic. RESULTS: Among patients who rated quality of life at the second visit as "a little better" and "much better," the mean change in pain score on a 10-cm VAS was reduced by 0.82 and 1.45 cm, respectively. For those whose quality of life changed to "a little worse" and "much worse," the pain scores increased by 1.90 and 3.69 cm. CONCLUSION: Our results suggest that future studies of the assessment and treatment of pain in this population should aim for a minimum reduction in pain score of 0.82 cm on a 10-cm VAS to achieve clinical improvement in quality of life.

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.
