As expected, most variables increased the risk of incurring CHE.
The observed frequency of most variables was close to the expected in each decile (as calculated by their χ scores), and there was no gradation across deprivation deciles for any variable.
If however, it is found that the end point is not normally distributed, (as expected for most variables in this study) univariate analysis will be conducted using non-parametric statistics.
As most variables included small sample numbers and thus not expected to be normally distributed, non-parametric tests were used.
However, in part because of the lower than expected patient recruitment and the higher than expected drop-out rate, a normal data distribution was not present for most variables.
Most variables are self explanatory.
The most variable, lap with 20 alleles, was expected because it is a highly variable locus when analyzed with multilocus enzyme electrophoresis (25 ).
As expected, exclusion of most variable positions from the analyses produced lower mean weighted substitution rates in both mt and nuclear genes.
The greatest differences in strengths of selection were found in the most variable regions of the S-RNases, as expected if these regions encode self-recognition specificities.
Despite sequencing regions expected to be among the most variable in the genome, we observed only five SNPs in 27 strains, corresponding to only three STs.
