Factors Showing No Associated Risk of CTS (Limited Evidence)
Limited evidence supports that race/ethnicity and female education level are not associated with increased or decreased risk of developing carpal tunnel syndrome (CTS).

Rationale
Education level among females showed no significant relationship to the development of CTS in one moderate quality (Bonfiglioli, 2007) and two low quality studies (Kaplan, 2008; Wright, 2014). Race/ethnicity showed no significant relationship to the development of CTS in one moderate quality study (Nathan, 2002).
