Table 2 relation between myasthenic crisis frequency and thymectomy

From: Frequency of myasthenic crisis in relation to thymectomy in generalized myasthenia gravis: A 17-year experience

  Thymectomized patients (n = 110) Non-thymectomized patients (n = 109) P value
Patients with myasthenic crisis (n = 62) 20 42* 0.001
Episodes of myasthenic crisis (n = 89) 25 64 0.016
  1. * This group had more probability of having crisis with an odds ratio of 2.8 (with 95% confidence interval of 1.5 to 5.2)
  2. Myasthenic crises were more prevalent in this group with a relative risk of 2.6 (with 95% confidence interval of 1.8 to 3.8)
