Subject | st: twoway line graph after stcompet by group |
Date | Tue, 30 Jul 2013 07:30:44 +0200 |
Dear Statalisters,I'd kindly appreciate your help regarding an issue with a competing risk analysis: I want to produce a graph showing the cumulative incidence functions for two groups using stcompet and twoway (accounting for death as a competing risk):
stset time_to_event, fail(outcome=1) stcompet cuminc_xvar=ci, by(xvar) compet1(2) separate cuminc_xvar if outcome==1, by(xvar) veryshortlabel twoway /// (line cuminc_xvar0 time_to_event, sort c(J)) /// (line cuminc_xvar1 time_to_event, sort c(J))Now my problem is that - when graphing the twoway plot - the cumulative incidence functions stop at the last event, but do not continue horizontally to the right of the graph (in parallel to the x-axis) as a stairstep function like in Kaplan-Meier normally does until the end of follow-up. If I produce the analogous graph using the Kaplan-Meier failure estimator followed by twoway line..., the curves continue nicely to the right until the end of follow-up (as expected). Any suggestions how to fix the cumulative incidence functions so they look analogous to the KM failure functions?
