GREP Exclude characters

Hello!

In my text the letter g means glossary. 

And I need DELETE all paragraph contains only numbers.  I mean, I need keep the paragraph if contain the cross references like the letter g and (See...)

Here you can see in color PINK the paragraph I need delete.

here is my code, but I don't know how can I EXCLUDE the other paragraph.

replaceTextUsingGREP ("+(\\d[–\\d, -]*\\d?) *","\r");
function replaceTextUsingGREP (input, output) { 
    app.findGrepPreferences = app.changeGrepPreferences = NothingEnum.nothing; 
    app.findGrepPreferences.findWhat = input;
    app.changeGrepPreferences.changeTo = output;
    var changedResults = app.activeDocument.changeGrep();
    app.findGrepPreferences = app.changeGrepPreferences = NothingEnum.nothing; 
}

Thanks so much!
