Significance between Kaplan Meier and a line - is it possible?

[Lytfi Krasniqi]

How can I check for significance between Kaplan Meier and a line when using addplot?
Obviously, Log rank test does not work.

The line consists of 15 (x,y) coordinates. It illustrates the survival of the danish background population, and do therefor not have a time-difference for the line.

The code for my graph is:

Sts graph, addplot(line bagY bagX)

You didn't get a quick answer. You'll increase your chances of a useful answer by following the FAQ on asking questions - provide Stata code in code delimiters (which you do), readable Stata output, and sample data using dataex.

You don't even give us the code you used to estimate your model. The term significance in a graph is problematic as well. Try reposting with the full information and see if you get a more helpful answer.
