Abstract

Meta-analysis (forest) plots are widely used to show the results from multiple individual randomized trials or observational studies that address the same question, including the assessment of screening markers. They show the between study spread of results and provide a summary estimate of the results from all the studies combined. We here illustrate the advantage of ordering study results by the magnitude of the effect and including a vertical shaded band encompassing the summary 95% confidence interval of the summary estimate to emphasize the uncertainty of the estimate in a way that is more prominent than only displaying a "diamond" around its value.

摘要

Meta分析（森林）图被广泛用于展示针对同一问题的多个个体随机试验或观察性研究的结果，包括筛查标志物的评估。它们展示了研究结果之间的差异，并提供了所有研究综合结果的汇总估计。我们在此说明了按效应大小对研究结果进行排序并纳入一个垂直阴影带的优势，该阴影带包含汇总估计的95%置信区间，以一种比仅在其值周围显示一个“菱形”更突出的方式强调估计的不确定性。
