Summary

DAGForge is a browser-based system designed to automate and audit the creation of causal directed acyclic graphs (DAGs) for biomedical causal analysis. This system addresses the traditionally manual process of connecting study variables to literature, evaluating causal claims, and preserving provenance. DAGForge generates a reproducible literature snapshot from free-text study concept descriptions, then employs an LLM-based reasoning module to produce structured pairwise causal judgments, grounded in verbatim evidence excerpts. These judgments are assembled into a constraint-checked graph, with each proposed edge including confidence estimates, provenance, and a reviewable rationale. The interface facilitates study specification, progress monitoring, evidence review, graph comparison, adjustment-set computation, and export. Evaluations show DAGForge achieves high edge recall on literature-based DAGs, providing verifiable evidence trails absent from LLM-only baselines, thereby reducing curation burden and making assumptions auditable for biomedical studies.

Key takeaway

For research scientists constructing causal DAGs in biomedical studies, DAGForge offers a critical tool to enhance rigor and efficiency. You can significantly reduce manual curation burdens while ensuring all causal assumptions are auditable and linked to verifiable literature evidence. This system allows you to generate robust DAGs, monitor progress, and compute adjustment sets with confidence, improving the design and interpretation of your studies.

Key insights

DAGForge automates auditable causal DAG construction for biomedical analysis by linking LLM-generated judgments to verifiable literature evidence.

Principles

• Causal DAGs require auditable provenance.
• LLMs can ground judgments in verbatim evidence.
• Constraint-checking improves graph reliability.
