If the patient is 'low risk' using the CHA 2 DS 2-VASc score (that is, 0 in males or 1 in females), no anticoagulant therapy is recommended. In males with 1 stroke risk factor (that is, a CHA 2 DS 2-VASc score=1), antithrombotic therapy with OAC may be considered, and people's values and preferences should be considered. [24]

Regression dilution arises if we are interested in the relationship between y and x, but estimate the relationship between y and w. Because w is measured with variability, the slope of a regression line of y on w is less than the regression line of y on x. Standard methods can fit a regression of y on w without bias.
Note that since the simple correlation between the two sets of residuals plotted is equal to the partial correlation between the response variable and X i, partial regression plots will show the correct strength of the linear relationship between the response variable and X i. This is not true for partial residual plots.
