Relevant feature of a sample of discontinued treatments were investigated, including status at the start and at the time of discontinuation. In a comparison between two discontinued groups, those patients who simply failed to return tended to have lower pretreatment PAR scores, and were more likely to have received non-extraction treatments in which removable appliances were employed. However, when discontinued treatments were compared to completed treatments undertaken in 1987/8, the completed cases were only reduced by two further PAR points.
对一组中断治疗病例的相关特征进行了调查，包括开始时和中断时的状况。在两个中断治疗组的比较中，那些 simply failed to return（此处疑有误，可能是“ simply failed to re - attend”，即“只是未能再次就诊”）的患者往往治疗前PAR评分较低，并且更有可能接受了使用可摘矫治器的非拔牙治疗。然而，当将中断治疗病例与1987/8年完成治疗的病例进行比较时，完成治疗的病例仅在PAR评分上又降低了两分。
