To compare the scientific methodology and quality of articles published in Anales Españoles de Pediatría and Medicina Clínica.
A stratified and randomized selection of 40 original articles published in 2001 in Anales Españoles de Pediatría and Medicina Clínica was made. Methodological errors in the critical analysis of original articles (21 items), epidemiological design, sample size, statistical complexity and levels of scientific evidence in both journals were compared using the chi-squared and/or Student's t-test.
No differences were found between Anales Españoles de Pediatría and Medicina Clínica in the critical evaluation of original articles (p > 0.2). In original articles published in Anales Españoles de Pediatría, the designs were of lower scientific evidence (a lower proportion of clinical trials, cohort and case-control studies) (17.5 vs 42.5 %, p 0.05), sample sizes were smaller (p 0.003) and there was less statistical complexity in the results section (p 0.03).
To improve the scientific quality of Anales Españoles de Pediatría, improved study designs, larger sample sizes and greater statistical complexity are required in its articles.
比较《西班牙儿科学年鉴》和《临床内科医学》上发表文章的科学方法和质量。
对2001年在《西班牙儿科学年鉴》和《临床内科医学》上发表的40篇原创文章进行分层随机选取。使用卡方检验和/或学生t检验比较两本期刊在原创文章批判性分析（21项）、流行病学设计、样本量、统计复杂性和科学证据水平方面的方法学错误。
在对原创文章的批判性评估方面，《西班牙儿科学年鉴》和《临床内科医学》之间未发现差异（p>0.2）。在《西班牙儿科学年鉴》上发表的原创文章中，研究设计的科学证据较低（临床试验、队列研究和病例对照研究的比例较低）（17.5%对42.5%，p<0.05），样本量较小（p<0.003），结果部分的统计复杂性较低（p<0.03）。
为提高《西班牙儿科学年鉴》的科学质量，其文章需要改进研究设计、增大样本量并提高统计复杂性。
