The Ross Growth Charts = the CDC Growth Charts = NCHS Growth Charts = the WHO Growth Charts. 

 

Those are EQUALS SIGNS, not html tags.  I was trying to say (not very clearly, I guess) that these growth charts are all the same.  The Ross Growth Charts EQUAL the CDC Growth Charts, which EQUAL the NCHS Growth Charts which EQUAL the WHO Growth Charts.  They're all the exact same charts, based on the same data.
