MAG and neuropathy: When focusing on the largest CSA measurements of the studied nerves, it was observed that patients with anti-MAG neuropathy exhibited a trend toward larger MN n-CSA and f-CSA than controls, with an increase in MN n-CSA of 5.43 mm3; however, this difference did not reach statistical significance (95% CI (−0.20, 11.06), p = 0.064).
