now reads:

Furthermore, in the Material and Methods section under subheading ‘Measurements.’,


“Similarly, the length of right main bronchi was to calculate the distance from left carina 2 to the carina and the length of left main bronchi was to measure the distance from right carina 1 to the carina.”


now reads:

Lastly, in the Results section,


“However, height between men and women was significantly different either.”
