Change in neuropsychological outcomes at age 7 years for 10-fold increases in mercury concentration. Results are from structural equation modeling (Fig. 2, top) of data from children with known postnatal exposures after adjustment for maternal Raven score, medical risk for neurobehavioral deficit, maternal and paternal education level, paternal employment, and day care.
