Table 2 shows the associations of self harm with and without suicidal intent at age 16 years with outcomes at age 18-21 years. The omnibus P values test for a difference in odds across the three levels of self harm. For each outcome in the table, the first two rows of odds ratios show associations between the outcome variable and history of self harm both without and with suicidal intent at age 16 years; the reference group for these odds ratios are adolescents who have never self harmed. The third row of odds ratios show differences in the outcome between those who self harmed with and without suicidal intent; the reference group for these odds ratios are adolescents with non-suicidal self harm. In this row, odds ratios greater than 1 indicate that a particular outcome is more strongly associated with suicidal self harm than with non-suicidal self harm; odds ratios less than 1.0 indicate the opposite.
