Suicide attempt was used as the reference category. Only variables with a significant crude value (p ≤ 0.02) were included in the multinomial analyses. Variables where only the proportion of unknown answers was significantly different between the groups were excluded. The appeal group did not differ from the suicide attempt group in any respect other than gender in the multinomial analyses, and therefore the figures are not included here.
