In medical CoT distillation, answer accuracy on MedQA-USMLE rises from 74.7% to 84.4% while step-level reasoning error increases from 30.6% to 50.3% per LLM-judge audit.
Scoping review of 134 studies on LLM-as-a-Judge in healthcare finds concentration in clinical decision support and NLP, frequent use of OpenAI models with prompt engineering, and moderate-to-strong human alignment where validated.
Counterfactual prompting effects on LLMs are often indistinguishable from those caused by meaning-preserving paraphrases, causing most previously reported demographic sensitivities to disappear under proper statistical comparison.

Better Accuracies, Worse Reasoning: A Step-Level Audit of Medical Chain-of-Thought Distillation
In medical CoT distillation, answer accuracy on MedQA-USMLE rises from 74.7% to 84.4% while step-level reasoning error increases from 30.6% to 50.3% per LLM-judge audit.
