The aim of this study was to quantify and assess the levels of evidence of research and review articles published in professional Physical and Rehabilitation Medicine journals with international circulations.
Quantitative analysis of articles published in Physical and Rehabilitation Medicine journals.
Selected articles from 7 Physical and Rehabilitation Medicine journals, published over a period of 6 years,were classified according to their level of evidence. Differences in the mean number of each type of article among journals and among years were analysed.
A total of 5,451 articles were included in this study,of which 636 (11.7%) were randomized controlled trials. Articles published with the highest frequency were those classified as Level III (n = 2,424, 44.5%), whereas “systematic reviews”were the least frequent (n = 164, 3.0%). Heterogeneity was found only in terms of distribution over journals.
The distribution of different types of article in Physical and Rehabilitation Medicine journals is similar to that in other disciplines. No increase in articles with a high level of evidence was found in the selected journals over the period of study.
本研究旨在定量评估具有国际发行量的专业物理医学与康复医学期刊发表的研究和综述文章的证据水平。
对物理医学与康复医学期刊发表的文章进行定量分析。
对 7 种物理医学与康复医学期刊在 6 年期间发表的文章进行分类，根据其证据水平进行分类。分析期刊和年份之间每种类型文章的平均数量差异。
本研究共纳入 5451 篇文章，其中 636 篇（11.7%）为随机对照试验。发表频率最高的是归类为 III 级（n=2424，44.5%）的文章，而“系统评价”的文章最少（n=164，3.0%）。仅在期刊分布方面存在异质性。
物理医学与康复医学期刊上不同类型文章的分布与其他学科相似。在所选择的期刊中，研究期间并未发现具有较高证据水平的文章数量增加。
