MG - Myasthenia gravis, AIDP - Acute inflammatory demyelinating polyradiculoneuropathy, IVIG - intravenous immunoglobulin, RNS - repetitive nerve stimulation, Functional outcome was ranked according to the adopted scale by Hughes: 0 healthy; 1 minor symptoms or signs, able to run; 2 able to walk >5 m without assistance, but unable to run; 3 able to walk >5 m with assistance; 4 bed- or chair-bound; 5 requiring assisted ventilation for at least part of the day; and 6 dead. “+” indicates the patient had precipitating factors from infectious disease. “-” indicates the patient did not have precipitating factors from infectious disease. As for the other parameters, “+” indicates positive findings, and “-” indicates negative findings.
