  • Abbreviation: df, degree of freedom.

  • * Model adjusted for year of diagnosis (1992-1993, 1994-1995, 1996-1997, 1998-1999, 2000-2002) and age at diagnosis (40-49, 50-59, 60-69 years). Likelihood ratio test of the effect of county in the model: df = 6, χ2 = 15.15, P = 0.0192.

  • Goodness-of-fit: under the hypothesis that the model fits, the deviance should follow a χ2 distribution with the specified degrees of freedom.
