Trouble with superscript citation font size

You want it the same size as the text around it?  usually the font of a superscript IS smaller than the surrounding text.  Certainly if you superscript text in word, that is what happens?  

see image attached.  in the first line, I inserted a superscripted EndNote (Nature output style) then I followed it with some text and used word to superscript it. (I then highlighted the EndNote inserted 1 in yellow). 

In the second line, I inserted “1now is the time” and superscripted it all with word.  

Not a lot of difference.  If anything the endnote one is very slightly larger?  – Word still shows the superscript of all of the above as 11 pts.
