The research company evaluated a two-year study on the use of asthma inhalers conducted by Agency X. Agency X had concluded that the data they collected were valid and the inhalers were effective in the treatment of certain asthmatic conditions. The research company followed the same procedure set up by Agency X. They used a double blind study with the same number of different patients, for the same time period. The research company determined that the conclusion of Agency X is valid and that the inhalers are effective. To ensure their results are free of bias, Agency X

• performed a two-year study.

• researched a previously published paper.

• had the research company use the same patients.

• sent the results to an independent research company.
