Hello,
I create a plot from a coxph object called fit.ads4:
plot(survfit(fit.ads4))

plot is located at:
https://www.dropbox.com/s/9jswrzid7mp1u62/survfit%20plot.png

I also create the following survfit statistics:

> print(survfit(fit.ads4),print.rmean=T)
Call: survfit(formula = fit.ads4)

   records      n.max    n.start     events     *rmean *se(rmean)
median    0.95LCL    0.95UCL
     203.0      100.0      100.0      103.0      486.7       24.4
 387.0      340.0      467.0
    * restricted mean with upper limit =  819


Questions:
1.  What is the cross mark in the plot ?
2.  How does the cross mark in the plot relate to either the "rmean" or the
"median" from survfit ?
3.  What is the meaning of the "restricted mean" ?  The "upper limit" noted
in the output is the "end of the observation period" (i.e., it is always
the Stop value in the Censored observation)

Thanks for taking the time to review

Steve
