Correction to: Mindray 3-directional NMT Module (a new generation “Tri-axial” neuromuscular monitor) versus the Relaxometer mechanomyograph and versus the TOF-Watch SX acceleromyograph

In the original publication of the article, the article note "Ashraf A. Dahaba and Zhao Yang Xiao equally contributed to the study and are both first authors." was published incorrectly. The correct statement should read as "Ashraf A. Dahaba and Zhao Yang Xiao equally contributed to the study and are both first authors and are both co-corresponding authors."
