Abstract
Acquired myasthenia gravis (MG) is an autoimmune disorder treated with cholinesterase inhibitors and a number of immunotherapies. Intravenous immunoglobulin (IVIG) is an expensive and commonly used immunotherapy for patients with an exacerbation of MG, but its effectiveness has only recently been demonstrated in a randomized clinical trial. This paper describes the study design, results, and limitations of a double-blind, randomized, placebo-controlled trial designed to definitively determine if IVIG benefits patients with MG who present with worsening weakness. Fifty-one patients with worsening weakness due to MG were randomized to receive either 2 g/kg of IVIG over 2 days or an equivalent volume of placebo (5% dextrose in water). The Quantitative MG Score (QMG Score) for Disease Severity, a validated clinical composite scale and the primary outcome measure in the study, was calculated by a masked observer 14 and 28 days after treatment. Patients treated with IVIG demonstrated a significant improvement in QMG Score for Disease Severity at day 14 and the response persisted at day 28. The largest clinical improvement occurred in patients with more severe disease. IVIG was well tolerated with no significant side effects observed. Given the observed efficacy and safety of IVIG demonstrated in this trial, future studies are necessary to determine if there is a role for interval IVIG treatments in chronic MG.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
