目标：确定有效的摘要格式对科学传播、系统审查、循证政策和医疗决策等多个领域至关重要。这项研究测试了在医学背景下，表格或纯文本格式是否能更好地理解不同选择的潜在危害和益处。设计：预先注册的纵向实验：受试者间因子2（信息格式）× 2主题（治疗性或预防性干预）关于理解和后来的回忆（const - spi 2018）。设置：纵向在线调查实验。参与者：2305名符合人口普查的英国居民，由YouGov调查公司招募。主要结果测量：六周后对危害和益处的理解和知识回忆。结果：事实框——简单的表格信息——与文本中的相同信息相比，六周后会导致更多的理解（d = 0.39）和更多的知识回忆（d = 0.12）。这些结果模式在两个医学主题之间以及在客观计算和教育的所有水平上是一致的。事实框被认为比文本更吸引人，在治疗决策、知情感或信任感方面，两种格式之间没有差异。结论：与纯文本对照相比，事实框的简表格式提高了对危害和益处的理解。有效的沟通支持知情同意和决策，并带来道德和实践优势。事实框和其他摘要格式可能在广泛的通信上下文中有效。
Objectives: identifying effective summary formats is fundamental to multiple fields including science communication, systematic reviews, evidence-based policy and medical decision-making. This study tested whether table or text-only formats lead to better comprehension of the potential harms and benefits of different options, here in a medical context. Design: pre-registered, longitudinal experiment: between-subjects factorial 2 (message format) x 2 topic (therapeutic or preventative intervention) on comprehension and later recall (CONSORT-SPI 2018). Setting: longitudinal online survey experiment. Participants: 2305 census-matched UK residents recruited through the survey panel firm YouGov. Primary outcome measure: comprehension of harms and benefits and knowledge recall after six weeks. Results: fact boxes-simple tabular messages-led to more comprehension (d = 0.39) and slightly more knowledge recall after six weeks (d = 0.12) compared to the same information in text. These patterns of results were consistent between the two medical topics and across all levels of objective numeracy and education. Fact boxes were rated as more engaging than text, and there were no differences between formats in treatment decisions, feeling informed or trust. Conclusions: the brief table format of the fact box improved the comprehension of harms and benefits relative to the text-only control. Effective communication supports informed consent and decision-making and brings ethical and practical advantages. Fact boxes and other summary formats may be effective in a wide range of communication contexts.
