From the article:
About one-third of attention deficit cases among U.S. children may be linked with tobacco smoke before birth or to lead exposure afterward, according to provocative new research.
About one-third may be linked with lead and/or tobacco? Wouldn't that mean then that TWO-THIRDS ARE NOT linked with lead and/or tobacco?
