P value for group comparison between subjects without UNE and with incident UNE.
*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 UNE are excluded.
BMI, body mass index; UNE, ulnar nerve entrapment.
