eMJA: Pharmaceutical advertisement claims in Australian medical publications Tim W Loke, Fong Chee Koh and Jeanette E Ward MJA 2002 177 (6): 291-293. Objective: To determine the quality of claims in advertisements published in Australian medical publications, describe how benefits and harms are presented, and examine the level of underpinning evidence. Design and setting: Audit of a consecutive three-month sample of advertisements appearing in six popular Australian medical publications. Main outcome measures: Proportion of advertisements with quantitative information; proportion of claims conveying clinical outcomes; where retrievable, level of underpinning evidence. Results: Of 1504 claims, 855 could be substantiated quantitatively. Of these, 45% were supported by compelling evidence (randomised controlled trials or better). Of 13 claims explicitly reporting quantitative outcomes, none provided the absolute risk reduction or the number needed to treat. Conclusions: Our audit invites greater diligence by pharmaceutical companies in substantiating their claims and greater vigilance among clinicians when reading them.
