Descriptive cross-sectional survey.
All papers listed under diagnosis and immunological headings of amebiasis in the Index Medicus from 1970 to 1988.
80 papers.
a: Adherence to methodologic criteria proposed for assessment of diagnostic test. b: presence of potential bias.
The adherence to methodologic criteria varied 1 to 55% of the papers. The comparison with a "gold standard" occurred in 40% the independent "blind" assessment occurred in 6% the setting for the study was described 1%. The study of an appropriate spectrum of disease was done in 11%. We were able to construct ROC curves with data from 37 papers and differences were observed among studies evaluating the same test. A high proportion of papers had potential bias.
The adherence to methodologic standards is poor in the papers analyzed in this series. Consequently the frequency of potential bias was high.
描述性横断面调查。
1970年至1988年《医学索引》中阿米巴病诊断和免疫学标题下列出的所有论文。
80篇论文。
a:遵循用于评估诊断试验的方法学标准的情况。b:潜在偏倚的存在情况。
遵循方法学标准的论文比例在1%至55%之间。与“金标准”进行比较的论文占40%,独立“盲法”评估的论文占6%,描述研究背景的论文占1%。对适当疾病谱进行研究的论文占11%。我们能够根据37篇论文的数据构建ROC曲线,并且在评估相同试验的研究之间观察到了差异。很大一部分论文存在潜在偏倚。
本系列分析的论文对方法学标准的遵循情况较差。因此,潜在偏倚的频率较高。
