Abbreviations: CDI, children’s depression inventory; SD, standard deviation.

^aGeneral depressive severity was assessed using the total score of CDI scale and classified into two groups, as suggested by Bang et al. [39].

^bThese patients were classified into two groups based on the median duration of illness.

^cSuicidal ideation was quantified using the total score of BSI scale and classified into two groups with the mediation score of 10.

^dSuicide risk was assessed using the total score of the NGASR scale and classified into two groups, following the findings of Cutcliffe et al. [41].

^eWe classified these patients into two groups: self-injurious and non-injurious individuals.
