Comparisons between regional estimates and the all-Wales rate
The rate of deaths by suspected suicide was statistically significantly higher in Mid and West Wales (15.7 per 100,000, 95% CI 13.1-18.7 per 100,000) compared with the all-Wales rate (12.6 per 100,000), as the confidence interval of the rate in Mid and West Wales did not overlap with the all-Wales rate. The rates in North Wales and South-East Wales were lower than the all-Wales rate, but this difference was not statistically significant, as the confidence intervals included the all-Wales rate.
Comparisons between regional estimates
The 95% confidence intervals of the regional rate estimates overlap but since two estimates with overlapping confidence intervals can still be statistically significantly different, further testing using the pairwise comparison of regions was done. It showed that the rate in Mid and West Wales was statistically significantly higher than the rate in North Wales and the rate in South-East Wales (see results in appendix).
From these data you can conclude that the rate of deaths by suspected suicide was statistically significantly higher in Mid and West Wales compared with the all-Wales rate, and with the rate in North Wales and South-East Wales.
