Kaplan Meier Plot - By group and sex

[LarsFolkestad]

Hello
Is it possible to create a KM plot by group and each group by sex?
i have tried
sts graph, by(group) by(sex)
the second by(sex) has been left out.

Lars,

Try:

sts graph, by(group sex)

Regards,
Joe

[LarsFolkestad]

Joe,
no i cannot seem to get that to work.
thank you though
Lars

Lars, what does Stata tell you when you try Joe's suggestion; his suggestion should work if both group and sex are numeric variables - are they?

[Steve Samuels]

As Rich says, what exactly do you mean by "doesnt work". Joe's advice is correct, e.g. try:

 webuse drug2
 gen young = age<47
 sts graph, by(drug young)

[LarsFolkestad]

You are absolutely correct. Don't know how i messed that up.
Now for question number two.
What if i only want to display data for one sex?

That's where Stata's -if- comes in.

sts graph if sex==1, by(drug young)
