 The cumulative incidence curve and the KM are not the same, when there
are multiple outcomes.  See the "etype" argument to survfit, which is
used to create CI curves (?survfit.formula).  For testing differences
between CI curves use the cmprsk library from Gray; it can also draw
curves by the survfit routine has a lot more flexibility.
