Abstract

fetched live from OpenAlex

This study examined whether multiple sclerosis (MS) patients (N = 3779) experience change in their perceived health-related quality of life (HRQOL) over a 5-year period, and investigated baseline factors that may be related to change in HRQOL. Data from the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry were used to address the study's research questions. Results for the physical and mental component scores of the 12-item Short Form Health Status Survey, version 2 (SF-12v2), indicated that most of the MS sample experienced no significant changes over a 5-year period. However, 40% and 36% of the sample experienced clinically significant declines in their physical and mental HRQOL, respectively, over the 5-year period. After controlling for baseline scores, having a lower education, having greater duration since disease diagnosis, not being employed, having a lower income, not receiving a disease-modifying therapy, and taking a greater number of prescription medications were significantly associated with a clinically significant decline in physical HRQOL. After controlling for baseline scores, not being married/partnered, experiencing a greater number of relapses, not being employed, having a lower income, and taking a greater number of prescription medications were significantly associated with a clinically significant decline in mental HRQOL. Overall, most of the MS sample remained stable in their HRQOL over time. However, approximately four out of every ten patients experienced a clinically important decline in their HRQOL. While the association was statistically significant, the sociodemographic and disease-related factors linked with decline did not strongly predict decline over a 5-year period.

Not 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.
