The use of low-calcium dialysate has been associated with decreased LV contractility and a corresponding decrease in blood pressure. It was further associated with a significant intradialytic decrease in blood pressure in both healthy and cardiac-compromised HD patients and patients with decreased LV ejection fraction.
intercept verb [T]. âº to âstop or âcatch something or someone that is on the way from one âplace to another so that it does not âreach the âintended âplace: to intercept a âletter The âball was intercepted by Grady.
The intercept (often labeled the constant) is the expected mean value of Y when all X=0. Start with a regression equation with one predictor, X. If X sometimes = 0, the intercept is simply the expected mean value of Y at that value.If X never = 0, then the intercept has no intrinsic meaning.In scientific research, the purpose of a regression model is to understand the relationship between predictors and the response. If so, and if X never = 0, there is no interest in the intercept.It doesnât tell you anything about the relationship between X and Y. You do need it to calculate predicted values, though.f X never = 0, then the intercept has no intrinsic meaning. In scientific research, the purpose of a regression model is to understand the relationship between predictors and the response. If so, and if X never = 0, there is no interest in the intercept.
