Abstract
BACKGROUND: In experimental autoimmune encephalomyelitis, inhibition of the renin-angiotensin system with angiotensin receptor blockers (ARBs) or angiotensin-converting enzyme (ACE) inhibitors resulted in a significantly ameliorated disease course. We evaluated the effects of ARBs and ACE inhibitors on the efficacy of interferon beta-1b in patients with relapsing-remitting multiple sclerosis (RRMS). METHODS: In this post hoc analysis of the BEYOND (Betaferon Efficacy Yielding Outcomes of a New Dose) study, clinical and MRI end points were compared between patients treated with interferon beta-1b 250 or 500 µg and concomitant ARBs or ACE inhibitors and patients treated with interferon beta-1b 250 or 500 µg only (reference group). RESULTS: Patients in the ARB group (n = 22) tended to have a higher relapse rate (0.48 vs. 0.23, p = 0.051) and a higher number of new gadolinium-enhancing lesions (0.6 vs. 0.3, p = 0.057) than patients in the reference group. Patients in the ACE inhibitor group (n = 49) also tended to have a higher relapse rate (0.29 vs. 0.22, p = 0.357). No differences were observed for the other end points. CONCLUSION: In the BEYOND study cohort, a concomitant medication with ARBs or ACE inhibitors did not have a beneficial effect in patients with RRMS treated with interferon beta-1b. As patients appeared to have a higher relapse rate, our results warrant further investigation.

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 it
