At 45 general-practice surgery sessions 200 patients in whom no definite diagnosis could be made were randomly selected for one of two procedures. Either they were given a symptomatic diagnosis and medications, or they were told that they had no evidence of disease and therefore they required no treatment. No difference in outcome was found between these two methods as judged by the return or not of the patient within one month and his statement that he did or did not get better.
在45次全科诊疗中,随机挑选了200名无法做出明确诊断的患者,让他们接受两种治疗方式中的一种。要么给他们做出症状性诊断并开药,要么告知他们没有疾病迹象,因此无需治疗。根据患者在一个月内是否复诊以及其表示病情是否好转来判断,这两种方法的结果没有差异。
