Abstract

fetched live from OpenAlex

OBJECTIVE: To examine laboratory testing adherence by persons initiating an oral disease-modifying therapy (DMT) for multiple sclerosis (MS). METHODS: Population-based health administrative and laboratory data were accessed in British Columbia, Canada, to identify everyone filling their first prescription for dimethyl fumarate (DMF), fingolimod or teriflunomide (2011-2015). The proportion of people adherent to each drug monograph's recommended laboratory monitoring schedule, pre- and on-DMT, was estimated. The association between patient characteristics and adherence was examined using multivariable logistic regression. RESULTS: A total of 1016 people were included (DMF 567, fingolimod 253 and teriflunomide 196). The proportions of people adherent to pre-DMT liver and lymphocyte tests ranged from 88% to 91% and 91% to 94%, respectively, while 77% adhered to pre-DMF urinalysis. Adherence to the first on-DMT liver test was 89% for DMF (within 6 months), 61% for fingolimod (within 3 months) and 40% for teriflunomide (within 1 month). Men were less likely than women to have pre-DMF urinalysis (adjusted odds ratio (aOR); 95% confidence interval (CI): 0.40-0.95) or on-DMF liver (aOR: 0.46; 95% CI: 0.23-0.95) or lymphocyte (aOR: 0.47; 95% CI: 0.22-0.98) tests. CONCLUSIONS: Adherence to recommended laboratory testing was high (>77%) before oral DMT initiation, but lower once on drug. There is a need to understand the long-term consequences of suboptimal laboratory monitoring and sex differences in the DMT-treated MS population.

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.
