compares the mean distance of branching point of the SBRN in different studies and the with calculated P values.

Studies

Mean distance of the Division point of the nerve, from the radial styloid

P value (CI = 95%)

Abrams et al (1992)

5.1 cm

0.81

Auerbach et al (1994)

6.0 cm

0.57

Robson et al (2008)

4.9 cm
