Reviewer’s report:  
 
I am satisfied with the authors' thorough responses to r eviewer concerns/suggestions as well as 
the reasonable revisions to improve the manuscript -- I find it more readable, with more 
appropriate coverage and conclusions that are supported by their findings. Good job!

specify direction of ascending trends based on GEFV grades for completeness' sake
