目标。我们试图解决在估计治疗风险降低时分母上的忽视（即只关注接受治疗和未接受治疗的患者死亡人数，而没有充分考虑患者总数），并分析图标阵列是否有助于理解。2008年7月和8月，我们在美国和德国进行了一次概率抽样调查。参与者接受了同样有效的治疗方案，但治疗和未治疗患者的总人数有所不同。在某些情况下，接受治疗的人数与未接受治疗的人数相等；在其他国家，这个数字或大或小。一些参与者收到了图标数组。参与者，特别是那些计算能力较低的参与者，在治疗风险降低认知方面表现出分母忽视。图标阵列是消除分母忽略的有效方法。我们发现，鉴于各国不同的医疗系统，跨文化差异是很重要的。理解数字信息的问题往往不在于头脑，而在于问题的表现形式。这些发现为定量医学数据的交流提供了合适的方法。[J] .公共卫生杂志，2009;99:2196-2202。doi: 10.2105 / AJPH.2009.160234)
Objectives. We sought to address denominator neglect (i.e. the focus on the number of treated and nontreated patients who died, without sufficiently considering the overall numbers of patients) in estimates of treatment risk reduction, and analyzed whether icon arrays aid comprehension.Methods. We performed a survey of probabilistic, national samples in the United States and Germany in July and August of 2008. Participants received scenarios involving equally effective treatments but differing in the overall number of treated and nontreated patients. In some conditions, the number who received a treatment equaled the number who did not; in others the number was smaller or larger. Some participants received icon arrays.Results. Participants-particularly those with low numeracy skills-showed denominator neglect in treatment risk reduction perceptions. Icon arrays were an effective method for eliminating denominator neglect. We found cross-cultural differences that are important in light of the countries' different medical systems.Conclusions. Problems understanding numerical information often reside not in the mind but in the problem's representation. These findings suggest suitable ways to communicate quantitative medical data.
