Bad presentation of medical statistics such as the risks associated with a particular intervention can lead to patients making poor decisions on treatment. Particularly confusing are single event probabilities, conditional probabilities (such as sensitivity and specificity), and relative risks. How can doctors improve the presentation of statistical information so that patients can make well informed decisions?
医学统计数据展示不当,比如与特定干预措施相关的风险,可能会导致患者在治疗决策上失误。特别容易混淆的是单一事件概率、条件概率(如敏感度和特异度)以及相对风险。医生如何才能改进统计信息的展示方式,以便患者能够做出明智的决策呢?
