Abstract：
UNASSIGNED: The purpose of this study was to examine the level of evidence (LOE) characteristics and associated factors that change over time in three leading prosthodontics journals.
UNASSIGNED: Articles published in The Journal of Prosthetic Dentistry (JPD), International Journal of Prosthodontics (IJP), and Journal of Prosthodontics (JP) in 2013 and 2020 were reviewed by eight independent reviewers. After applying exclusion and inclusion criteria, the number of authors, the corresponding author\'s educational degree, corresponding author\'s origin in each clinical research article were recorded. The included articles were rated by reviewers according to the level of evidence criteria and proposed level of evidence-associated factors. Descriptive statistics, univariable, and binary logistic regression analysis were performed to investigate dependent variables and potentially associated factors. All independent variables with a significant effect were analyzed by using a multivariable test. The entry and exit alpha level were set at αE = 0.15. The statistical significance was set at α = 0.05.
UNASSIGNED: A total of 439 articles from 3 selected journals for the years studied met the inclusion criteria. The percentages of level 1, 2, 3, 4, and 5 articles were 2.7 %, 11.4 %, 9.6 %, 13.4 % and 62.9 %, respectively. Univariable analysis results demonstrated significant associations related to the number of authors (P = 0.005), the corresponding author\'s educational degree (P = 0.022), and the corresponding author\'s geographic origin (P = 0.042). Multivariable analysis results demonstrated significant associations related to the number of authors (P = 0.002), and the corresponding author\'s geographic origin (P = 0.014).
UNASSIGNED: The number of authors, CA degree, and CA origin had a significant association with the LOE of included prosthodontic studies. Although there was an increase in the number of publications from 2013 to 2020, the level of evidence trend shows no improvement over the years.

摘要：
■这项研究的目的是检查三个主要的口腔修复学期刊中证据水平（LOE）特征和随时间变化的相关因素。
■发表在“修复牙科杂志”(JPD)上的文章，国际口腔修复学杂志(IJP)，和口腔修复学杂志（JP）在2013年和2020年由8名独立审稿人进行了审查。在应用排除和纳入标准后，作者的数量,相应作者的教育程度，记录每篇临床研究文章中相应作者的来源。审稿人根据证据标准水平和拟议的证据相关因素水平对纳入的文章进行评级。描述性统计，单变量,和二元logistic回归分析用于调查因变量和潜在相关因素.所有影响显著的自变量均采用多变量检验进行分析。进入和退出α水平设置为αE=0.15。统计显著性设定为α=0.05。
■在所研究的年份中，来自3种选定期刊的439篇文章符合纳入标准。1、2、3、4、5级文章的百分比为2.7％，11.4%,9.6%,13.4%和62.9%，分别。单变量分析结果显示与作者数量显著相关(P=0.005),通讯作者的教育程度(P=0.022)，和相应作者的地理来源(P=0.042)。多变量分析结果显示与作者数量显著相关(P=0.002),和相应作者的地理来源(P=0.014)。
■作者的数量，CA学位,CA起源与纳入口腔修复研究的LOE有显著关联。尽管从2013年到2020年出版物数量有所增加，但证据水平趋势多年来没有改善。
