许多调查和队列研究都使用了随机零点血压计血压装置（RZS）来测量受试者的血压，并评估血压在预测心血管事件中的价值。最近的研究使用了自动血压测量设备（AOD），系统地测量了比RR更高的血压值，阻碍了这些研究之间的可比性。2000-2003年，作者在德国进行的一项队列研究中随机使用了RZS和AOD。该分析旨在比较不同器械的血压值，并开发一种算法，将血压值估计值从一种器械转换为另一种器械。在2，365名年龄在45-75岁之间的受试者的随机化子集中，每名受试者按照随机化顺序使用每种器械测量三次。两种器械之间的收缩压平均差（AOD-RZS）为3.9 mmHg，舒张压为2.6 mmHg。作者发现，包括年龄、性别和血压水平的线性回归模型可用于将RZS血压值转换为AOD血压值，反之亦然。结果可能有助于更好地比较使用不同血压设备的流行病学研究中的血压值。
Many surveys and cohort studies have used a random-zero sphygmomanometer blood pressure device (RZS) to measure subjects' blood pressure and to assess the value of blood pressure in predicting cardiovascular events. Recent studies used automated oscillometric blood pressure devices (AODs) that systematically measure higher blood pressure values than RZSs do, hampering comparability of values between these studies. In 2000-2003, the authors randomly used both an RZS and an AOD in an ongoing cohort study in Germany. This analysis aimed to compare blood pressure values by device and to develop an algorithm to convert estimates of blood pressure values from one device to the other. In a randomized subset of 2,365 subjects aged 45-75 years, each subject was measured three times with each device in a randomized order. The mean difference (AOD-RZS) between the devices was 3.9 mmHg for systolic blood pressure and 2.6 mmHg for diastolic blood pressure. The authors found that linear regression models including age, sex, and blood pressure level can be used to convert RZS blood pressure values to AOD blood pressure values, and vice versa. Results may help to better compare blood pressure values in epidemiologic studies that used different blood pressure devices.
