Abstract
BACKGROUND: Local injection of botulinum toxin type A is first-line treatment of blepharospasm, cervical dystonia, and hemifacial spasm; however, there is uncertainty about the optimal dose of toxin for each indication as well as dose-conversion ratios that should be used when switching products in clinical practice. OBJECTIVE: The goal of this study was to compare the safety, effectiveness, and duration of clinical effect of BOTOX and Dysport and Dysportdagger after drug switching (Dysport to BOTOX) among patients with movement disorders. METHODS: A total of 48 patients diagnosed with blepharospasm (n = 27), cervical dystonia (n = 12), or hemifacial spasm (n = 9) were evaluated during a single-arm, crossover-design study in which each patient was his/her own historical control using a 5:1 or 4:1 conversion ratio of Dysport to BOTOX units. Patients were assessed (using Jankovic, Visual Analog Scale, general pain scale, Toronto Western Spasmodic Torticollis Rating Scale [TWSTRS] scores) after the last injection of Dysport and the first injection of BOTOX. Moreover, each patient kept a diary during treatment to track onset and duration of therapeutic effect. RESULTS: Although BOTOX and Dysport were both clinically effective, this effect was more significant with BOTOX compared to Dysport based on TWSTRS for cervical dystonia (p = 0.012), and Jankovic scores for blepharospasm (p = 0.006). Longer duration of effect also was noted with BOTOX than with Dysport (blepharospasm, 62.2 days vs 47.4 days (p = 0.001); cervical dystonia, 64.3 days vs 44.6 days (p = 0.014); hemifacial spasm, 65.1 days vs 41.8 days (p < 0.014), respectively). Of the 48 patients, 19 experienced at least one adverse drug reaction (ADR) during Dysport treatment, with the most commonly reported ADRs being ptosis for blepharospasm and hemifacial spasm and neck weakness for cervical dystonia. No patient reported an ADR during BOTOX treatment. CONCLUSIONS: Results suggest therapeutic effectiveness is enhanced with BOTOX compared to Dysport at a dosing ratio between 5:1 and 4:1 (Dysport:BOTOX). Safety and duration of therapeutic effect also are enhanced with BOTOX. Further research is needed.

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
