Comparisons between area deprivation estimates and the all-Wales rate
The rate of deaths by suspected suicide was statistically significantly lower in residents who lived in the least deprived areas at 9.5 per 100,000 (95% CI 7.2-12.4 per 100,000) compared with the all-Wales rate (12.6 per 100,000). The rates were higher than the all-Wales rate in residents who lived in the most deprived, next most deprived and next least deprived areas, but the confidence intervals around the rates overlapped with the all-Wales rate so these were not statistically significant.
Comparisons between area deprivation estimates
The 95% confidence intervals of the deprivation rate estimates overlap each other, 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 rates of suspected suicide in residents who lived in the most deprived and next most deprived areas (13.9 per 100,000 and 13.7 per 100,000) were statistically significantly higher than the rate in residents who lived in the least deprived areas (9.5 per 100,000).
From these data you can conclude that the rate of deaths by suspected suicide was statistically significantly higher in residents in the most deprived areas compared with the least deprived areas.
