Nothing of value.
(They did start another study for control for genetic factors, but those aren't the most important)
Article says
The long-term associations held even after the researchers took other common factors into account. "These findings imply that basic childhood skills, independent of how smart you are, how long you stay in school, or the social class you started off in, will be important throughout your life," say Ritchie and Bates.
Which implies that they controlled for socioeconomic status. However, the actual paper appears to be behind a paywall. Therefore I don't know what's in it, beyond what this article tells me.
