Figure 2. Primary Outcome in a Study of the Effect of Internet-Delivered vs In-Person Cognitive Behavioral Therapy (CBT) on Obsessive-Compulsive Disorder Symptoms in Children and Adolescents.

Figure 2.

A, Boxes represent the interquartile range of the 25th and 75th percentiles, the middle line represents the median, the circles with connecting lines represent the mean values, the whiskers extend to the highest and lowest values within 1.5 times the interquartile range, and dots represent outliers. Children’s Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) scores range from 0 to 40, with higher scores indicating more severe symptoms. The posttreatment assessment was 16 weeks after the pretreatment assessment, and the follow-up assessments were 3 months and 6 months after the posttreatment assessment. Nonresponders at the 3-month follow-up were offered additional in-person CBT between the 3-month follow-up and the 6-month follow-up. B, Stepped-care treatment was considered noninferior to in-person CBT because the 1-sided 97.5% CI of the mean difference was below the prespecified margin of 4 points (dotted line) on the CY-BOCS.
