How much did the government regulate business practices during the gilded age?

A law was passed in 1890 called the Sherman Act under Harrison presidency, yet it did not lead to the breaking up of cartels and monopolies. The Gilded Age(1877-1900) was followed by the Progressive Era which saw some effort to regulate big business practices despite the fact that some scholars for instance contest this vision and claim that the regulation put forward by Theodore Roosevelt actually strengthened cartels.
