To the Editor Fralick and colleagues1 provide a summary and meta-analysis of the association between concussion and suicide outcomes. This study summated the evidence on suicidality following concussion, and we commend the authors on their comprehensive review. The authors reported a relative risk of suicide associated with a history of concussion of 2.03 (95% CI, 1.47-2.80; P < .001).1 To our knowledge, absolute risk increases were not reported or interpreted in this article.1
