目的：根据研究设计，对美国四种主要妇产科杂志的论文进行分类比较。方法：对1997年5月出版的《美国妇产科杂志》、《妇产科》、《妇科肿瘤学》、《生育与不孕症》(F&S)各一年的期刊进行综述。补充问题被排除在审查之外。确定了致力于观察性研究设计与实验研究设计的文章的百分比，并评估了证据的质量，包括与其他研究设计相比，随机对照试验的严重程度。结果：共纳入文献1517篇。临床研究论文的平均比例为90.4%。动物研究的百分比分别为10.7%(AJOG)、1.1%(O&G)、1.1%(GO)和4.2%(F&S)(X(2)p<；0.001)。基础科学论文分别占5.3%、1.9%、6.5%和7.5%(P=0.007)。观察性论文的平均比例为68.2%，实验论文的平均比例为14.1%。随机对照试验分别占随机对照试验的8.7%、11.1%、3.3%和9.5%(X(2)p=0.008)。结论：大多数综述的研究是临床的，超过一半的文章是观察性的。在美国预防服务工作组评级系统下，随机对照试验被给予最高评级-I类证据。产科和妇科学的研究人员可能并不完全支持循证临床实践的努力，这一点从向主要产科和妇科杂志提交的文章和发表的文章中得到了反映。版权所有(C)2001 S.Karger AG，巴塞尔。
Objective: To classify and compare articles, based on the study design, in four leading US obstetrics and gynecology journals. Methods: One year of each journal, American Journal of Obstetrics and Gynecology(AJOG), Obstetrics and Gynecology (O&G), Gynecologic Oncology (GO), and Fertility and Sterility (F&S), beginning May 1997, was reviewed. Supplementary issues were excluded from review. The percentage of articles devoted to observational versus experimental study design was determined, and the quality of evidence was assessed including how heavily randomized controlled trials were represented versus other study designs. Results: 1,517 articles were reviewed. The average percentage of clinical research articles was 90.4. The percentage of animal studies were 10.7 (AJOG), 1.1 (O&G), 1.1 (GO) and 4.2 (F&S) (chi (2) p < 0.001). There were 5.3, 1.9, 6.5, and 7.5% basic science articles, respectively ((2) p = 0.007). The average percentage of observational articles was 68.2 and that of experimental articles was 14.1. The percent ages of total articles classified as controlled experimental were 10.9 (AJOG), 14.6 (O&G), 5.1 (GO), and 15.2 (F&S) (chi (2) p = 0.01) There were 8.7, 11.1, 3.3 and 9.5% randomized controlled trials, respectively (chi (2) p = 0.008). Conclusions: The majority of research reviewed was clinical, and more than half of the articles were observational. Under the US Preventative Services Task Force rating system, the randomized control trial is given the highest rating - class I evidence. The drive toward evidence based clinical practice may not be fully supported by researchers in obstetrics and gynecology, as reflected by submissions to and publications in the major obstetrics and gynecology journals.
