Fig. 3From: Identifying molecular mediators of the relationship between body mass index and endometrial cancer risk: a Mendelian randomization analysisDAG demonstrating the proposed causal interactions of BMI, SHBG, fasting insulin and bioavailable testosterone on endometrial cancer (overall and the endometrioid histological subtype). DAG = directed acyclic diagram, BMI = body mass index, SHBG = sex hormone-binding globulin.
