Table 2 Risk ratios for suicide-attempts and self-injury by group (no pain vs. recurrent pain)

From: The association of self-injurious behaviour and suicide attempts with recurrent idiopathic pain in adolescents: evidence from a population-based study

  M1: unadjusted M2: adjusted M3: fully-adjusted
Self-injury RR (95% CI) RR (95% CI) RR (95% CI)
 1–3 times per year 2.956 (2.423–3.606)*** 2.367 (1.933–2.899)*** 1.433 (1.154–1.780)***
 >3 times per year 6.039 (4.440–8.215)*** 4.570 (3.351–6.232)*** 1.816 (1.264–2.608)***
Suicide attempts RR (95% CI) RR (95% CI) RR (95% CI)
 One suicide attempt 3.630 (2.840–4.640)*** 2.833 (2.190–3.665)*** 1.402 (1.075–1.829)*
 Multiple suicide attempts 5.450 (3.809–7.799)*** 4.077 (2.830–5.874)*** 1.751 (1.178–2.603)**
  1. Risk ratios expressed with respect to references categories for suicide attempts (no suicide attempt) and SI (no SI) in respondents with recurrent pain compared to those not reporting recurrent pain; Model 1: unadjusted, only adjusted for 116 clusters (schools); Model 2: adjusted for sociodemographic variables: gender, age, school type, and living situation at home; Model 3: further adjustment for all sub-scales of the YSR except for somatic complaints.
