How We Study Early-Life Factors in Autism

A research poster was presented at the 2026 Society for Causal Inference Conference (Salt Lake City, Utah). The poster describes how researchers study early-life factors and autism when experiments are not possible. Because researchers cannot ethically or practically conduct experiments during pregnancy or early childhood, understanding these relationships requires careful use of observational data and explicit assumptions. The protocol introduces a transparent, community-informed framework for comparing multiple factors within a single analysis and for interpreting what conclusions can—and cannot—be drawn from the results.
