The original article contains an error. In the material and methods section, the Ethics committee and Institution information appears as XXX. The corrected sentence must read: “Approval was obtained from the Ethics Committee of Istanbul University, Cerrahpasa Medical Faculty with the decision dated 05.01.2017 and numbered 2017-6241.”

The original article has been corrected.
