在以往的研究中，二尖瓣环运动（MAM）和左心室的选举分数（EF）之间的关系，线性关系已被提出。在434例患者的荟萃分析中，我们发现这种关系是非线性的，线性回归模型在MAM的较低范围内高估了EP。这种关系可以用S函数更好地描述，并受到年龄和心脏大小的影响。
In previous studies of the relation between mitral annulus motion (MAM) and left ventricular election fraction (EF), a linear relationship has been suggested. In this meta-analysis of 434 patients, we show that the relation is nonlinear and that a linear regression model overestimates EP in the lower range of MAM. The relation is better described by an S function and is influenced by age and heart size.
