Abstract
BACKGROUND AND PURPOSE: Chronic inflammatory demyelinating polyneuropathy (CIDP) causes weakness which adversely impacts function and quality of life (QOL). CIDP often requires long-term management with intravenous or subcutaneous immunoglobulin. The Polyneuropathy and Treatment with Hizentra® (PATH) study showed that subcutaneous immunoglobulin (SCIG) was efficacious in CIDP maintenance. Here, patient-reported outcomes in patients on SCIG are assessed. METHODS: Subjects stabilized on intravenous immunoglobulin were randomly allocated to receive weekly 0.2 or 0.4 g/kg bodyweight of 20% SCIG (IgPro20) or placebo. Overall QOL/health status was assessed using the EuroQoL 5-Dimension (EQ-5D) health profile and visual analog scale, treatment satisfaction was assessed with the Treatment Satisfaction Questionnaire for Medicine (TSQM) and work-related impact was assessed with the Work Productivity and Activity Impairment Questionnaire for General Health (WPAI-GH). The EQ-5D health profile was assessed in terms of the percentage of subjects maintained or improved at week 25 of SCIG therapy on each of the EQ-5D domains versus baseline after intravenous immunoglobulin stabilization. TSQM and WPAI-GH were assessed by median score changes from baseline to week 25. RESULTS: In total, 172 subjects were randomized to placebo (n = 57), 0.2 g/kg IgPro20 (n = 57) and 0.4 g/kg IgPro20 (n = 58). Significantly higher proportions of IgPro20-treated subjects improved/maintained their health status on the EQ-5D usual activities dimension, and in additional dimensions (mobility and pain/discomfort) in sensitivity analyses. TSQM and WPAI-GH scores were more stable with IgPro20 treatment compared with placebo. CONCLUSIONS: IgPro20 maintained or improved QOL in most subjects with CIDP, consistent with the PATH study findings that both IgPro20 doses were efficacious in maintaining CIDP.

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
