Reliability and repeatability of blood pressure (BP) measurements performed by both a local nurse and a control nurse visiting all five study areas in the Finnish Multicentre Study were analysed. As an objective control, Rose's tape recordings were played at least three times during the study period to each nurse. It was found that the nurses differed from each other with variations of 2.5 mm Hg, 54.6 mm Hg and 17.9 mm Hg in the recordings of systolic, diastolic Korotkoff's IV (KIV) phase and diastolic KV phase sounds respectively, in assessing the tape. Correlation coefficients between the systolic BP and diastolic BP measurements made by the local and control nurses in 3-year-old children varied from 0.10 to 0.72 and from -0.16 to 0.46 respectively. Correlation coefficients in 6-18-year-old subjects between systolic, diastolic KIV and diastolic KV BP measurements made by the control and local nurses varied from 0.69 to 0.81, from 0.42 to 0.63 and from 0.38 to 0.58 respectively. All of the nurses had a significant terminal digit preference and it was pronounced in two of them. Because of these findings it was concluded that comparisons of BP values in different areas should be done cautiously.
对芬兰多中心研究中当地护士和对照护士在所有五个研究区域进行的血压测量的可靠性和重复性进行了分析。作为客观对照，在研究期间，至少向每位护士播放三次罗斯的录音带。结果发现，在评估录音带时，护士之间存在差异，收缩压、舒张压柯氏音IV（KIV）期和舒张压KV期声音的记录差异分别为2.5毫米汞柱、54.6毫米汞柱和17.9毫米汞柱。当地护士和对照护士对3岁儿童收缩压和舒张压测量的相关系数分别在0.10至0.72和-0.16至0.46之间。对照护士和当地护士对6至18岁受试者收缩压、舒张压KIV期和舒张压KV期血压测量的相关系数分别在0.69至0.81、0.42至0.63和0.38至0.58之间。所有护士都有明显的末位数字偏好，其中两位尤为明显。基于这些发现，得出结论：不同地区血压值的比较应谨慎进行。
