Fig. 1: Cumulative incidences and 95% confidence intervals of ADHD for individuals born 1981–2005 using medical records up to 2012 stratified by year of birth.

Cumulative incidences are shown for (A) the general population (n = 1,560,901 individuals), (B) individuals with at least one full-sibling diagnosed with ADHD (n = 24,476 individuals), (C) individuals with at least one parent diagnosed with type-2 diabetes (n = 5557 individuals). Confidence intervals are reported as cumulative incidence estimates at a given age for a specific year of birth +/− 1.96 × standard error.
