Reproducibility of the <scp>Six‐Minute</scp> Walk Test in Children and Youth With Juvenile Idiopathic Arthritis
Bibliographic record
Abstract
Objective While the 6‐minute walk test is increasingly being used in research to evaluate submaximal exercise capacity of children with juvenile idiopathic arthritis (JIA), psychometric properties with this population have not been well evaluated. We undertook this study to evaluate reproducibility (agreement and test–retest reliability) and to determine standard error of measurement (SEM) and smallest detectable difference (SDD) in children and youth with JIA. Methods Participants (n = 22, mean ± SD age 13.1 ± 1.1 years, 63.6% female) completed a 6‐minute walk test as part of their routine clinical assessment, and then repeated the 6‐minute walk test at mean ± SD 8 ± 1.2 days later, in the same clinical setting with the same rater. Results The intraclass correlation coefficient (95% confidence interval) was 0.86 (0.66–0.94); the SEM and SDD were 23.5 and 65.1 meters, respectively. Conclusion These results provide evidence of good–excellent reproducibility of the 6‐minute walk test with children and youth with JIA and support the use of the 6‐minute walk test as a measure of submaximal exercise capacity in clinical practice and research.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
