3.2. Comparing suicide note writers and non-note writers
A bivariate analysis of socio-demographic and clinical factors in
note writers and non-note writers was carried out (Table 1). We
found females (p¼0.006) and Caucasians (p¼0.003) were more
likely to leave a suicide note. Suicide note-writers were also more
likely to use non-violent methods (p¼0.031). Only gender
(Wald¼7.8; OR¼2.8, 95% CI¼1.4–5.7, p¼0.005) and ethnicity
(Wald¼6.0; OR¼13.7, 95% CI¼1.7–111.0; p¼0.014) remained significant
predictive variables of suicide note writing in the logistic
regression model. Most of the non-Caucasians (1 versus 15) did
not leave a suicide note which is very different from the Caucasians
(85 versus 109).
