P.041 3 year longitudinal health related quality of life in a spinal muscular atrophy cohort
Bibliographic record
Abstract
Background: Spinal Muscular Atrophy (SMA) is a rare, genetic disorder marked by motor neuron degeneration, causing progressive muscle weakness. SMA significantly impacts patients and their families. This study investigates HRQOL in a longitudinal SMA cohort. Methods: The study used the Canadian Neuromuscular Disease Registry to examine HRQOL in children aged 6-10 years with genetically confirmed SMA. HRQOL was evaluated using the PedsQL™ Measurement Model. This tool is validated in children and adolescents with various health conditions. The PedsQL Neuromuscular Module which has been validated in SMA was also used. Results: Eight participants completed the PedsQL generic and Neuromuscular Module at timepoint 1 (TP1) and 2 (TP2). The mean scores at TP1 were 49.66 (SD=5.05) for the generic PedsQL and 61.06 (SD=18.37) for the Neuromuscular Module. At TP2, mean scores increased to 59.32 (SD=13.08) and 74.86 (SD=9.88), respectively. The overall mean change over the two timepoints was +9.66 (SD=15.16) for the Generic PedQL and +13.80 (SD=23.03) for the Neuromuscular Module. Six participants were on disease modifying treatment. Conclusions: HRQOL scores in SMA patients improved over the study period. The enhancement in HRQOL may indicate the positive impact of diseases modifying treatments of SMA that became available during that time.

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.
