For multi-agent LLM pipelines on multimodal medical referral from real inpatient records, requiring agents to exchange typed logical edges (causal cascade, mutual reinforcement, exclusion, conditional context) in a shared reasoning graph instead of free-form dialogue raises referral F1, and the causal-chain edge type carries most of that gain.

Capability: Getting more from several models than from one

Observed on

952 real inpatient cases over 37 departments, four modality agents plus an expert arbitration agent, DeepSeek-V3 backbone, zero-shot, four-option multiple choice; gains saturate at.

  • Validated by: Referral F1 on 952 real inpatient cases: 95.3% vs 91.4% for MMA and 92.6% for ToR multi-agent baselines and 89.7% for GPT-5; replacing the graph with natural-language output cost 5.1 F1, removing inter-agent collaboration 6.1, removing the knowledge base 2.3; removing the cascade relation alone dropped F1 to 90.6%, more than any other relation type. Measured on one self-constructed dataset from a single hospital, one backbone for all baselines, with module and relation-type ablations and a human-scored reasoning rubric; [truncated]

Notes

Drafted from the paper by a model and filed unreviewed. Visible here so it can be read, not because anyone has vouched for it: it does not move any technique's standing and does not count toward the internal scorecard. Drafted confidence: low. Falsifier as drafted: A matched comparison in which free-form multi-agent dialogue with the same agents, knowledge base and round budget reaches the same referral F1, or in which removing the cascade relation costs no more than removing any other relation type.
