背景：尽管引用因子是为了比较相互竞争的期刊而商业化开发的，但它仍被用于评估科学研究成果。本研究的目的是利用已发表的肺癌临床研究中的随机试验，确定引用因子与试验方法学质量之间是否存在关联。
材料与方法：由欧洲肺癌工作组（ELCWP）进行的9项系统综述中所包含的所有随机试验均使用两种质量量表（查尔默斯量表和ELCWP量表）进行评估。
结果：181篇文章符合条件。ELCWP总体质量评分和查尔默斯质量评分的中位数分别为61.8%和49.0%，相关系数（r(s)）为0.74（P<...此处原文似乎不完整）
Background: Citation factors are applied to assess scientific work despite the fact that they were developed commercially in order to compare competing journals. The aim of the present study was to determine whether there is a relationship between citation factors and a trial's methodological quality using published randomised trials in lung cancer clinical research.Material and methods: All of the randomised trials included in nine systematic reviews performed by the European Lung Cancer Working Party (ELCWP) were assessed using two quality scales (Chalmers and ELCWP).Results: One hundred and eighty-one articles were eligible. The median overall ELCWP and Chalmers quality scores were 61.8% and 49.0%, respectively, with a correlation coefficient (r(s)) of 0.74 (P
