Abstract

We characterized the quantity and quality of graphs in all pharmaceutical advertisements, in the 10 U.S. medical journals. Four hundred eighty-four unique advertisements (of 3,185 total advertisements) contained 836 glossy and 455 small-print pages. Forty-nine percent of glossy page area was nonscientific figures/images, 0.4% tables, and 1.6% scientific graphs (74 graphs in 64 advertisements). All 74 graphs were univariate displays, 4% were distributions, and 4% contained confidence intervals for summary measures. Extraneous decoration (66%) and redundancy (46%) were common. Fifty-eight percent of graphs presented an outcome relevant to the drug's indication. Numeric distortion, specifically prohibited by FDA regulations, occurred in 36% of graphs.

摘要

我们对美国10种医学期刊上所有药品广告中的图表数量和质量进行了分析。在总共3185则广告中,有484则不同的广告包含836页彩印页面和455页小号字体页面。彩印页面面积的49%为非科学图表/图像,0.4%为表格,1.6%为科学图表(64则广告中有74张图表)。所有74张图表均为单变量展示,4%为分布图,4%包含汇总指标的置信区间。图表中存在大量无关装饰(66%)和冗余内容(46%)。58%的图表展示了与药物适应症相关的结果。数字失真现象(这是美国食品药品监督管理局(FDA)法规明确禁止的)出现在36%的图表中。
