Funding Source Bias Regarding Adverse Effects

Studies of inhaled corticosteroids, medications frequently prescribed for asthma and other respiratory problems, appear less likely to find adverse effects if they are funded by pharmaceutical companies than if they are funded by other sources.

Their use has been associated with potentially harmful decreases in the stress hormone cortisol, decreases in bone mineral density and growth suppression.

Overall, 34.5 percent of pharmaceutical-funded studies and 65.1 percent of studies with other funding sources found a significant difference in adverse effects between individuals assigned to inhaled corticosteroid groups and those who were not.

Read details of this funding source adverse effects bias study.
