  1. The table presents the mean nerve fiber density (i.e. fibers per section), the percentage difference of positive fibers within the muscle tissue, and the distribution (either in association with myocytes or in the connective tissue surrounding the myocytes).
  2. There are microbiopsies from the masseter muscle from six men and six women, while there are microbiopsies from seven men and seven women from the tibialis muscle.
  3. There were no significant differences.
