Figure 4 shows the relationship between frequency of self-harm and suicidal thoughts or plans. Compared to those who had self-harmed once, those who had self-harmed 2–5 times were nearly twice as likely to have thought of killing themselves (OR = 1.86, 95%CIs: 1.34-2.58), those who had self-harmed 6–10 times were more than three times as likely to have done (OR = 3.08, 95%CIs: 1.84, 5.17) and those who had self-harmed more than ten times were nearly five times as likely to have done (OR = 4.93, 95%CIs: 3.06, 7.94). Similarly, compared to those who had self-harmed once, those who had self-harmed 2–5 times were more likely to have made plans to kill themselves (OR: 2.59, 95%CIs: 1.61, 4.17), those who had self-harmed 6–10 times were more than three times more likely to have done (OR:3.18, 95%CIs: 1.69, 6.00) and those who had self-harmed more than 10 times were approximately eight times more likely to have done (OR: 8.64, 95%CIs: 5.12, 14.60).
