Likelihood ratio test= 39.6  on 10 df,   p=1.95e-05
Wald test            = 32.6  on 10 df,   p=0.000312
Score (logrank) test = 41.4  on 10 df,   p=9.73e-06,   Robust = 25.7  p=0.00418

  (Note: the likelihood ratio and score tests assume independence of
     observations within a cluster, the Wald and robust score tests do not).
