When other agencies funded high-quality research, similar action was taken. In 2009, Branas et al published the results of a case-control study that examined whether carrying a gun increases or decreases the risk of firearm assault. In contrast to earlier research, this particular study was funded by the National Institute on Alcohol Abuse and Alcoholism. Two years later, Congress extended the restrictive language it had previously applied to the CDC to all Department of Health and Human Services agencies, including the National Institutes of Health.

These are not the only efforts to keep important health information from the public and patients. For example, in 1997, Cummings et al used state-level data from Washington to study the association between purchase of a handgun and the subsequent risk of homicide or suicide. Similar studies could not be conducted today because Washington State's firearm registration files are no longer accessible.
