- Estimates are shown ordered by decreasing SMR. For males
is the posterior mean relative risk estimated using the fully BYM model with clustering and heterogeneity random effects; for females, only the heterogeneity term was considered. The column 'Significance' must be read as "p-value ρ
i
of the null hypothesis of no increased risk H0 : θ
i
= 1 is strictly less than the indicated value". The areas reported in the table are those where θ
i
> 1 and ρ
i
< 0.05, i.e. the risk excess resulted to be statistically significant. It is worth noting that due to the approximation used for the construction of confidence intervals, the lower end of 95% CI
SMR
may fall below unity (although a few decimal places only) even when significance is reached.
