评估和整合临床试验报告的质量对于实践循证医学是必要的。特别是,数值数据对于了解临床试验研究的强度和质量至关重要。在本文中,我们提出了对已发表的临床试验报告中的数值数据进行标准化的正式表示,以及我们为开发计算工具来捕获和可视化这种表示而做出的努力。该方法包括两个方面:用于精确定义数值背后的实验背景的过程模型;电子表格是一种直观且熟悉的工具,用于组织数字数据。我们使用非小细胞肺癌 (NSCLC) 的临床试验报告证明了这一表述。我们进行了初步评估,以确定这种形式对于确定临床试验的特征、质量和意义的有用性。我们的初步结果表明,该表示具有足够的表现力,可以捕获已发表论文中报告的数字信息。
Assessing the quality of and integrating clinical trial reports are necessary to practice evidence-based medicine. In particular, the numerical data is essential to understanding the strength and quality of the clinical trial study. In this paper, we present a formal representation for standardizing numerical data in published clinical trial reports, and our efforts towards developing computational tools to capture and visualize this representation. The approach includes two aspects: a process model used to precisely define experimental context behind the numerical value; and a spreadsheet, an intuitive and familiar tool used to organize numerical data. We demonstrated this representation using clinical trial reports on non-small cell lung cancer (NSCLC). We performed a preliminary evaluation to determine the usefulness of this formalism for identifying the characteristics, quality and significance of a clinical trial. Our initial results demonstrate that the representation is sufficiently expressive to capture reported numerical information in published papers.
