Addendum: In the Research Letter entitled "The
World Trade Center Disaster and Intrauterine Growth Restriction" published
in the August 6, 2003, issue of THE JOURNAL (2003;290:595-596), the following
should have been added to the next to last paragraph in the "Methods" section:
"One potential participant was not included in this study because the child
was diagnosed with a disorder of presumed genetic origin."
