  • P value for group comparison between subjects without CTS and with incident CTS.

  • *P value for group comparison; independent sample t-test used for age, Mann-Whitney U test used for BMI, systolic and diastolic blood pressure (BP), χ2 test for dichotomous variable. Participants with prevalent CTS are excluded.

  • BMI, body mass index; CTS, carpal tunnel syndrome.
