A group of 200 patients who presented in general practice with symptoms but no abnormal physical signs and in whom no definite diagnosis was made were randomly selected for one of four consultations: a consultation conducted in a "positive manner," with and without treatment, and a consultation conducted in a "non-positive manner," called a negative consultation, with and without treatment. Two weeks after consultation there was a significant difference in patient satisfaction between the positive and negative groups but not between the treated and untreated groups. Similarly, 64% of those receiving a positive consultation got better, compared with 39% of those who received a negative consultation (p = 0.001) and 53% of those treated got better compared with 50% of those not treated (p = 0.5).
一组200名患者，他们在全科医疗中表现出症状但无异常体征且未做出明确诊断，被随机分配到四种会诊之一：以“积极方式”进行的会诊，分为接受治疗和未接受治疗两种情况；以及以“非积极方式”进行的会诊，称为消极会诊，也分为接受治疗和未接受治疗两种情况。会诊两周后，积极组和消极组患者的满意度存在显著差异，但治疗组和未治疗组之间没有差异。同样，接受积极会诊的患者中有64%病情好转，而接受消极会诊的患者中这一比例为39%（p = 0.001），接受治疗的患者中有53%病情好转，未接受治疗的患者中这一比例为50%（p = 0.5）。
