They mean they thought parental permissiveness could be a confounder, so they divided the subjects into subgroups where the level of parental permissive was the same and found that within each sub-group, more candy as kids meant more crime as adults. For example, they looked at all the kids with strict parents and found that within that group more candy meant more crime, same with permissive parents, etc. Submit Answer Tries 0/1 8.
