We conducted a systematic literature search in Medline to assess the proportion of observational intervention studies appreciating confounding bias in peer-reviewed medical literature from 1985 through 2005. This study shows only 9% of all papers on observational intervention studies published in peer-reviewed medical journals mention any of the terms (confounding, adjustment, or bias) indicating appreciation of confounding.
我们在Medline中进行了系统的文献检索，以评估1985年至2005年间同行评审医学文献中认识到混杂偏倚的观察性干预研究的比例。这项研究表明，在同行评审医学期刊上发表的所有关于观察性干预研究的论文中，只有9%提到了任何表明认识到混杂的术语（混杂、调整或偏倚）。
