5. Re: p-value of survdiff (score: 1): Author: Thomas Lumley <tlumley@u.washington.edu>; Date: Mon, 12 Mar 2007 07:37:44 -0700 (PDT); AFAICS the curves don't actually cross in your graph. You have 4 events in the smaller group and 1 in the larger group, and a weakly significant p-value looks plausible to me.
