I am helping a colleague that wants to describe the relation between
vascular wall stiffnes and wall tension for 30 patients. In a simple
linear regression analysis the association is almost significant, but
the scatterplot does not show the association so clear. The points are
very scattered around the regression line.
After adjustment for age and sex the relation becomes strongly
significant. I would like to make a scatterplot with added regression
lines of the association after adjustment for age and sex. I guess I
can use confidence limits to illustrate the strong association, but is
it also possible to show the points after adjustment?
Regards
Roland
