From: Estimation of health effects of prenatal methylmercury exposure using structural equation models
Path diagram for the association between indicators of mercury exposure and childhood neurobehavioral functions. The latent true mercury exposure is assumed to be affected by the covariates and maternal pilot whale meat intake. The two mercury biomarkers are assumed to depend on the true exposure and a random error. True prenatal mercury exposure affects the latent motor function and the verbally mediated function which are measured through the eleven neurobehavioral test scores.
