2. Fig 1
Kaplan-Meier curves of patients who experienced complete remission (CR) of ocular myasthenia gravis (OMG) after undergoing extended transsternal thymectomy (ETT). The CR was defined using the standard of strict complete remission (SCR) (A, C) and the broader standard of general complete remission (GCR), which included asymptomatic patients receiving low-dose single-drug immunosuppressive therapy (B, D). Patients on whom analysis was done for probability of SCR versus time after surgery (C) and probability of GCR versus time after surgery (D) were grouped according to duration of symptoms, with those whose symptoms had lasted 12 months or less showing greater improvement after ETT in terms of both SCR and GCR. The numbers below the figures denote the number of patients at risk in each group. Values of p < 0.05 were considered significant. (CI = confidence interval; HR = hazard ratio.)
