Branger pointed out that the documentation on lifetable command in latest
analysis was faulty. An updated version of commands.htm has been uploaded
and can be found at:
http://www.epidata.dk/commands.htm#lifetabgrp

The file will be added to install versions later.

Estimation options:
 /time=x :Calculate Survival estimate at indicated time value (values)
 /p25 p50 p75 :Calculate Time span estimates at Quartiles and Median of
Survival Proportions (0.75 0.5 0.25)
 /t : Log-rank test and Hazard Ratio (only relevant with /by)
 /ref=x : Indicates value of /by variable to use as reference for
comparisons when the difference from reference is estimated for /time /p
and /t options

The option /G has been replaced with /NG to hide the graph., but was
incorrect in the documentation.
Hide/show:

    * /NG do notshow the Kaplan Meier plot
    * /NT : do not show summary documentation table
    * /NOLT: do not show lifetable
    * /E0 /E1 /E2 /E3 /E4 : show results with this number of decimals
    * /NOCI : Hide confidence intervals in tables and graph (e.g. if
graphs overlap for groups)
