LogiMed-RoB benchmark reveals error compounding in LLM medical logic

Researchers have introduced LogiMed-RoB, a benchmark based on Cochrane Risk of Bias 2.0 expert logic to evaluate large language models across 860 randomized controlled trials. Testing on 10 state-of-the-art models revealed a severe error compounding effect, despite the top model achieving 98.88% atomic consistency.
