# st: SV: stcompet and cumulative incidence at a specific point in time

```Dear Enzo.

I've encountered the same problem, but was advised to use the psudovalue approach with the -stpci-, were you generate pseudo values at the time you are interested in:

gen cevent=(dssstatus==2)
label variable cevent "competing risk event"
stpci cevent, at(1 2 3 4 5)

Hope this helps.

Best regards

Emne: st: stcompet and cumulative incidence at a specific point in time

Hi All,

Is there a Stata command that can be used to list (at specific time
points  e.g. -sts list, at (0 (1) 5)-)
the cumulative incidence function with confidence intervals from a
competing risk analysis (after the ?stcompet- command)?

As far as I know there is not a command.
The following code should approximately obtain what you need supposing
that the -ci- is the name of the variable containing the cumulative
incidence:

forval i = 1(1)5 {
qui su _t if _t<=`i'
local tobs = `r(max)'
qui su ci if _t<=`i'
local ciat = `r(max)'
if `i'==10 di _col(5) "at" _col(18) "Obs Time" _col(33) "Cum Inc"
di _col(5) `i' _col(20) `tobs' _col(35) `ciat'
}

Best

Enzo
