CTL, healthy controls; DEP, depressive symptoms without self-harm thoughts; EPDS, Edinburgh Postnatal Depression Scale; ns, no difference; SHT, self-harm thought.
Pearson Chi-square tests for categorical variables, with post hoc tests given overall significance (Bonferroni corrected within specific outcome) for categorical variables and one-way ANOVA for continuous variables.
Significance (p < 0.05): adifference between SHT and CTL group; bdifference between DEP and CTL group; and cdifference between SHT and DEP group.
