A convenience sample of all medical journals found in a medical clinic was reviewed for pharmaceutical advertisements. Ads were present in 25 (96%) of the 26 journals. Ad space varied from 0-34% (mean 12) in research, and 9-48% (mean: 36) in nonresearch journals. In 23 (88%) journals, individual ads consisted of more than one page. Colorful glossy insert-ads, of up to nine pages, were seen in 18 (69%) journals. Six (23%) journals contained more advertising than editorial pages. Many ads were longer than the longest article in that journal. Medical journals devote considerable space to pharmaceutical ads. Excessive pharmaceutical advertising may bias the journals' owners and readers and may be distracting and annoying.
对一家诊所内所有医学期刊的便利样本进行了审查，以查找药品广告。26种期刊中有25种（96%）登有广告。研究类期刊的广告版面占比从0%至34%不等（平均为12%），非研究类期刊的广告版面占比为9%至48%（平均为36%）。23种（88%）期刊的单则广告篇幅超过一页。18种（69%）期刊登有多达9页的彩色光面插页广告。6种（23%）期刊的广告篇幅超过了编辑内容。许多广告比该期刊中最长的文章还要长。医学期刊为药品广告留出了相当大的版面。过多的药品广告可能会使期刊所有者和读者产生偏见，还可能分散注意力并令人厌烦。
