Notes: First four columns taken directly from Coleman’s meta-analysis [6]. The first column presents the studies used, grouped by the comparison group reported in the meta-analysis. The unintended birth group in the first column was labeled “Unintended pregnancies” in Coleman’s Figure 3, which we have corrected here. The second column shows the mental health outcome used in Coleman’s meta-analysis: Alco= Alcohol measure, Marij = Marijuana measure, Anx = Anxiey measure, Dep = Depression measure, Suic ideation = suicidal ideation, Suic = Suicide. The fifth column shows the RCPsych rating if it was included in the RCH Psych review. If it was not included in the RCPsych review, this was noted and so was the reason for exclusion. Reasons for exclusion in column 5: ICPMH = inappropriate control of prior mental health, ICMH = inappropriate control for mental health, ICMHM = inappropriate control of mental health measure, NMEG = not mutually exclusive groups, ICG = inappropriate comparison group, NUD = no useable data. The sixth column addresses whether the study contributed an effect independent of all other effects in the meta-analysis (Yes signifies it did, No signifies it did not). The seventh column presents the data used in the study.
