From: A systematic review and analysis of long-term outcomes in attention deficit hyperactivity disorder: effects of treatment and non-treatment

Figure 4

Untreated participants with attention deficit hyperactivity disorder (ADHD) compared with non-ADHD controls. The percentage of the total number of outcomes is provided for each bar. The total number of studies represented in each bar is shown in parentheses. The green bar shows the percentage of outcome results reported as similar (26% of outcomes; 89 studies) in untreated participants with ADHD compared with non-ADHD participants. The blue bar shows the percentage of outcome results reported as poorer (74% of outcomes; 244 studies) in untreated participants with ADHD compared with non-ADHD participants. The sum of the numbers of studies shown under each bar does not equal the total number of studies represented in this figure; several studies reported some outcomes that were similar to control and some outcomes that were poorer than controls. Therefore these studies are represented in both types of outcome.
