Many clinical research studies involve paired outcome data, which consist of 2 measurements of the same variable in the same patient at 2 times. This article examines ways that researchers can graphically report data from such studies, meeting the dual goals of showing the experience of each patient while comparing differences between treatment groups. I emphasize the importance of hybrid parallel line plots, examine several useful variations of them, and provide Stata code to make them.
许多临床研究涉及配对的结果数据，这些数据由同一位患者在两个时间点上的同一个变量的 2 次测量组成。本文探讨了研究人员如何以图形方式报告此类研究的数据，从而实现展示每个患者的经验并比较治疗组之间差异的双重目标。我强调了混合平行线图的重要性，研究了它们的几种有用变体，并提供了制作它们的 Stata 代码。
