First recurrent suicidal behaviour (attempted suicide or dying by suicide) of Axis I group. The primary and secondary outcome measures were the incidence proportion of the first episode of recurrent suicidal behaviour (attempted suicide or dying by suicide) at 6 and 12 months after randomisation, respectively

	Primary outcome 6 months (n = 734)	Secondary outcome 12 months (n = 692)
Intervention vs control	21/354 vs 44/380	35/338 vs 50/354
Unadjusted risk ratio	0.51 (0.31–0.84), P = 0.009	0.73 (0.49–1.10), P = 0.133
(Imputed missing data) *	0.49 (0.30–0.81), P = 0.005	0.72 (0.48–1.08), P = 0.112
Adjusted risk ratio +	0.53 (0.32–0.87), P = 0.012	0.75 (0.50–1.12), P = 0.156
(Imputed missing data) §	0.52 (0.32–0.86), P = 0.010 *	0.72 (0.48–1.08), P = 0.110

^*age and sex adjusted

The data included the number of events/population for the intervention participants (assertive case management) or for the control participants (enhanced usual care), or the risk ratio (95% CI). ^*Risk ratios with data imputed for individuals who missed the assessment. ⁺Risk ratios adjusted by use of regression models for the randomisation factors of sex, age, and history of previous suicide attempts before the current episode. §Risk ratios with data imputed for individuals who missed the assessment and adjusted by use of regression models for the randomisation factors of sex, age, and history of previous suicide attempts before the current episode
