科学领域:

产科和妇科
产妇和胎儿医学
临床风险预测

背景情况:

孕前 (PE) 在全球显著增加孕产妇的发病率和死亡率.
确定临床风险因素和预测不良结果对于及时干预至关重要.

研究的目的:

确定PE妇女在孕产妇中出现不良后果的临床风险因素.
开发和验证预测模型来评估PE患者的不良结果的风险和时间.

主要方法:

在中国对1400名PE妇女进行了回顾性队列研究,随机分为培训 (70%) 和验证 (30%) 组.

Regression Toward the Mean

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...
