(a). The mean standardized family genetic risk scores (FGRS) (± 95% confidence intervals) for major depression (MD), anxiety disorders (AD), bipolar disorder (BD), schizophrenia (SZ), alcohol use disorder (AUD), drug use disorder (DUD), attention deficit-hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in individuals with MD only, AD only and those with both MD and AD – the comorbid cases. The sample size of these three groups is provided at the top of the figure. These FGRS scores are depicted on the Y-axis. The colors/shades of the columns reflect the class of the disorders: Red/Black – Internalizing, Yellow/Dark Gray – Psychotic, Green/Medium Gray – Substance Use, and Blue/Light Gray – Developmental. Under each column for the MD only and AD only samples, we list the signed magnitude of the difference observed between that FGRS and the parallel one for the comorbid cases, with a positive difference reflecting a higher FGRS in the comorbid sample. The second number reflects the p value of the difference. Given the large number of tests performed, we set a p < 0.0001 as a threshold for statistical significance. (b). The mean standardized FGRS (± 95% confidence intervals) for MD, AD, BD, SZ, AUD, DUD, Attention Deficit-Hyperactivity Disorder (ADHD) and ASD in individuals with AUD only, DUD only and those with both AUD and MD – the comorbid cases. The sample sizes of these three groups are provided at the top of the figure. These FGRS scores are depicted on the Y-axis. The colors/shades of the columns reflect the class of the disorders: Red/Black – Internalizing, Yellow/Dark Gray – Psychotic, Green/Medium Gray – Substance Use, and Blue/Light Gray – Developmental.

The mean standardized FGRSs (± 95% confidence intervals) for MD, AD, BD, SZ, AUD, DUD, Attention Deficit-Hyperactivity Disorder (ADHD) and ASD in individuals with ADHD only, ASD only and those with both ADHD and ASD – the comorbid cases.

The mean standardized FGRSs (± 95% confidence intervals) for MD, AD, obsessive −compulsive disorder (OCD), BD, SZ, AUD, DUD, Attention Deficit-Hyperactivity Disorder (ADHD) and ASD in individuals with AD only, OCD only and those with both AD and OCD – the comorbid cases. The sample sizes of these three groups are provided at the top of the figure. These FGRS scores are depicted on the Y-axis. The colors/shades of the columns reflect the class of the disorders: Red/Black – Internalizing, Yellow/Dark Gray – Psychotic, Green/Medium Gray – Substance Use, and Blue/Light Gray – Developmental.

The second number reflects the p value of the difference. Given the large number of tests performed, we set a p < 0.0001 as a threshold for statistical significance. (e). The mean standardized FGRSs (± 95% confidence intervals) for MD, AD, BD, SZ, AUD, DUD, ADHD and ASD in individuals with DUD only, ADHD only and those with both DUD and ADHD – the comorbid cases.
