Abstract

fetched live from OpenAlex

OBJECTIVE: To identify and characterize drug-induced liver injury (DILI) associated with IFN-β in multiple sclerosis (MS) using recommended criteria. METHODS: This retrospective, mixed methods design included a cohort of IFN-β exposed MS patients from British Columbia (BC), Canada and a series of DILI cases from other Canadian provinces and two adverse drug reaction (ADR) networks (USA and Sweden). Associations between sex, age and IFN-β product, and DILI were explored in BC cohort using Cox proportional hazard analyses. Characteristics, including the time to DILI, were compared between sites. RESULTS: In BC, 18/942 (1.9%) of IFN-β exposed MS patients met criteria for DILI, with a trend toward an increased risk for women and those exposed to IFN-β-1a SC (44 mcg 3 × weekly) (adjusted Hazard Ratios: 3.15;95% CI:0.72 - 13.72, p = 0.13 and 6.26;95%CI:0.78 - 50.39, p = 0.08, respectively). Twenty-four additional cases were identified from other sites; the median time to DILI was comparable between BC and other Canadian cases (105 and 90 days, respectively), but longer for the ADR network cases (590 days, p = 0.006). CONCLUSIONS: Approximately 1 in 50 IFN-β exposed patients developed DILI in BC, Canada. Identification of DILI cases from diverse sources highlighted that this reaction occurs even after years of exposure.

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.
