We illustrate these capabilities with a case study of formaldehyde exposure and leukemia using a cluster of four papers that feature very different approaches and partly conflicting conclusions. AIA2 successfully identifies major points of agreement and contention, discusses the robustness of the evidence for causal claims, and recommends future research directions to address current uncertainties.

The quality of this emulation depends, in part, on the availability and accessibility of data for each component of the TTF. Yet one overarching challenge with using EHR data is that unstructured fields, such as clinical encounter notes, contain copious details on the patient yet require additional steps to extract if needed in the conduct of the study. Natural language processing (NLP) represents a spectrum of methods to assist with automating this extraction, from simpler rule-based methods to machine learning and artificial intelligence approaches that can handle complex language structures. What follows is a discussion on how NLP methods can augment information and data for researchers looking to estimate a treatment effect using EHR data via the TTF to emulate the hypothetical clinical trial.

This paper provides a constructive answer. It introduces three key metrics — Interventional Probability of Causation (IPoC), Causal Assigned Shares (CAS), and Preventable Risk Fraction (PRF) curves — to help overcome the limitations of traditional association-based metrics, such as Population Attributable Fractions (PAFs), which are sometimes misused to answer interventional causal questions. The tools introduced here provide scenario-specific, individual-level predictions of risk reductions grounded in mechanistic causality rather than associations. Using case studies of benzene exposure and acute myeloid leukemia (AML), smoking and lung cancer, and blood lead levels and mortality, we demonstrate how PRF curves quantify the potential risk-reduction benefits caused by exposure reductions at both the individual and population levels, even under uncertainty or heterogeneity. Monte Carlo simulations capture inter-individual variability, and scenario analyses identify practical thresholds where additional exposure reductions yield minimal added benefit. These methods can provide evidence-based assessments of how specific exposure reductions affect risk. By shifting the focus from attribution to prevention of harm, this framework can potentially advance risk assessment, policy development, and legal decision-making. It offers a simple, easily visualized, transparent, and scientifically rigorous approach to identifying causally effective interventions and quantifying risk-reduction benefits.</div></div>","PeriodicalId":36311,"journal":{"name":"Global Epidemiology","volume":"9 ","pages":"Article 100206"},"PeriodicalIF":0.0,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144106091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
