Reply: Pediatric Guillain-Barré Syndrome and Autonomic Dysfunction

We would like to thank Kurtoglu et al. for their kind interest and useful comments about our article.^1,2 We completely agree that those factors that could affect the autonomic nervous system should be excluded in any research that involves evaluating heart rate variability. Of course we have implemented and mentioned all these exclusion criteria (age> 18, history of or receiving treatment for hypertension, affected by other CNS disease, intubated patients needing any sedative drugs or intravenous inotropic support, patients with significant structural heart disease with or without cardiac arrhythmias, history of diabetes mellitus and abnormalities in thyroid function) in the original research proposal and final thesis. Unfortunately we have neglected to mention these criteria in our published article. We apologize for this oversight.
