Genetically predicted UA was associated with lower odds BD (OR = 0.999, 95% CI 0.997–1.000; p = 0.025), and higher odds ADHD (OR = 1.002, 95% CI 1.001–1.003; p = 0.004); CAT was associated with lower odds AN (OR = 0.903, 95% CI 0.816–0.999; p = 0.048); albumin was associated with higher odds ASD (OR = 1.162, 95% CI 1.035–1.304; p = 0.011) (Figure 2). This evidence concerns the gene ALB and attention deficit-hyperactivity disorder.
