Initial model
Motor function -0.938 0.543 0.0841
Verbal function -1.742 0.516 0.0007
Adjusted for local dependence
Motor function -0.983 0.512 0.0550
Verbal function -1.624 0.497 0.0011
Also adjusted for item bias
Motor function -1.028 0.530 0.0525
Verbal function -1.631 0.499 0.0011
ML estimation after full adjustment
Motor function -1.004 0.542 0.0639
Verbal function -1.777 0.531 0.0008
Inclusion of incomplete cases, full adjustment
Motor Function -1.034 0.487 0.0339
Verbal Function -1.623 0.517 0.0017

True mercury exposure is expressed on the scale of the cord blood concentrations, the latent motor function is on the scale of NES finger tapping with preferred hand, while the verbally mediated function is expressed on the scale of the Boston Naming Test score with cues.
