背景和目标：具有压力数据的时空表示的高分辨率测压是在过去10-15年中发展的技术。我们比较了时空和传统的线图表示的测压数据在一组医学生的能力方面的用户来一个快速和准确的诊断和评估用户的偏好的2种形式的数据显示。研究方法：在标准化的纸质和电子教程之后，60名医学生将一系列运动性疾病的30个典型示例分类为线图（10个传感器，包括“虚拟套管”）和时空图格式（来自16个传感器）。吞咽以随机顺序电子呈现。评估的准确性和速度进行了比较之间的2种形式的数据呈现，以及偏好的主观评级。结果表示为平均值的平均标准误差。结果如下：基于时空格式数据的分类通常更正确（89% +/- 1.2% vs 86% +/-1.3%，P = 0.002），并且比折线图格式更迅速地提供正确诊断（25 +/- 2.9秒vs 31 +/- 3.2秒，P <0.001）。68%的研究人群更喜欢时空呈现。结论：当数据以时空形式呈现时，由测压新手个体进行的测压数据分析比以线图格式呈现时更快、更准确。此外，用户更喜欢时空图。测压数据的时空呈现可能更容易被患者和“非专家”医生群体理解。
Background & Aims: High-resolution manometry with spatiotemporal representation of pressure data is a technique that has developed during the past 10-15 years. We compared spatiotemporal and traditional line plot representation of manometry data in a group of medical students in terms of the ability of the user to come to a rapid and accurate diagnosis and evaluated user preferences for the 2 forms of data display. Methods: After standardized paper-based and electronic tutorials, 60 medical students classified 30 typical examples of a range of motility disorders in both line plots (10 sensors, including a "virtual sleeve") and spatiotemporal plot format (derived from 16 sensors). Swallows were presented electronically in random order. The accuracy and speed of the assessment were compared between the 2 forms of data presentation, as well as a subjective rating of preference. Results are presented as mean standard error of the mean. Results: Classifications based on data presented in spatiotemporal format were more often correct (89% +/- 1.2% vs 86% +/- 1.3%, P = .002), and correct diagnoses were provided more promptly (25 +/- 2.9 seconds vs 31 +/- 3.2 seconds, P < .001) than in line plot format. Sixty-eight percent of the study population preferred the spatiotemporal presentation. Conclusions: The analysis of manometry data by manometry-naive individuals is faster and more accurate when data are presented in spatiotemporal than in line plot format. In addition, users preferred the spatiotemporal plots. Spatiotemporal presentation of manometric data is likely to be more easily understood by patients and the "non-expert" physician community.
