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.
If you have dummy variables in your model, though, the intercept has more meaning. Dummy coded variables have values of 0 for the reference group and 1 for the comparison group. Since the intercept is the expected mean value when X=0, it is the mean value only for the reference group (when all other X=0).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.
