Prevalence represented the observed value for each demographic grouping and the mid-point of these was taken as the expected value for each separate test. Statistically significant results are highlighted in bold font. Due to the large number of tests performed some statistical significance is expected to occur by chance. To combat this, only tests returning a p value less than 0.02 were considered significant.
