Statistics for attempted suicide during follow-up among 3678 female bipolar patients.

Distribution of study variables, bivariate statistics, and adjusted odds ratios with 95% confidence interval (95% CI) for attempted suicide during follow-up among 3678 female bipolar patients recorded in the BipoläR 2004–2011 and followed-up annually 2005–2012.
aFatal or non-fatal attempted suicide during follow-up, as registered in the BipoläR at annual follow-ups.
bChi-square values derived from two-by-two tables, hence df = 1.
cWhen previous suicide attempts was explanatory variable, the logistic regression model included the potential confounder age as well as all variables in the table that had a significant p-value in bivariate comparison. When other variables in the table were explanatory variables, the variable previous suicide attempts was omitted.
dCategorical variable. Bipolar disorder type 1 was reference category in the chi-square tests and in the multiple regression.
eBipolar disorder of unspecified type.
fSchizoaffective disorder of bipolar type.
gFirst-degree relatives; data available for a subset of the cohort only.
hData available for a subset of the cohort only.
iBefore 18 years of age; data available for a subset of the cohort only.
jOne cell had expected count less than 5; therefore, Fisher's exact test was used instead of the chi-square test.
kFor instance, illness, injury, or poisoning.
lFor instance, family-, work- or economy-related.
mDirected towards people; data available for a subset of the cohort only.
