Likelihood ratio test= 37.0  on 10 df,   p=5.76e-05
Wald test            = 28.6  on 10 df,   p=0.00146
Score (logrank) test = 37.6  on 10 df,   p=4.45e-05,   Robust = 23.1  p=0.0104

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