In an apparently double blind crossover study, two experienced measurement technicians were able to identify many of the treatment periods. They most often correctly identified aspirin, a drug with prominent effects and side effects. It is argued that in many circumstances it is better to use a blind observer who is not concerned with the giving of treatment or the collection of side effects.
在一项明显的双盲交叉研究中，两名经验丰富的测量技术人员能够识别出许多治疗阶段。他们最常正确识别出阿司匹林，一种具有显著疗效和副作用的药物。有人认为，在许多情况下，最好使用不参与治疗给药或副作用收集的盲法观察者。
