Fig. 2. Cumulative incidence of conversion to generalized MG according to the RNS test. The Kaplan-Meier survival curves show the cumulative incidence of conversion to generalized MG from ocular symptom onset according to the RNS test. The cumulative incidence of conversion to generalized MG was higher in the RNS-test-positive group than in the RNS-test-negative group (p=0.001). MG: myasthenia gravis, RNS: repetitive nerve stimulation.
