NSD, Non significant difference; ^aFor the purpose of this review, an exact McNemar test using the data presented by the authors was performed for a pre-/post assessment of the treatment effect on PTSD diagnosis in the intervention group in six studies where the authors did not perform such evaluation.¹⁴^,¹⁸^,²⁰^,²⁵^,²⁶^,³⁸^{; b}For the purpose of this review, an independent chi-square test using the data presented by the authors was performed for a between-group comparison of the treatment effect on PTSD diagnosis in two studies where the authors did not perform a statistical test for such assessment.¹⁴^,²⁵^{; c}Behavioral difficulties did not include ADHD or hyperactivity disorder.
