How do I treat the results of Fit as text?

I would like to take the results of Fit (or any FittedModel) and treat them as text, including making substitutions for the variables. But I can't figure out how to do this.

For example

"Subscript[I, m]/Subscript[I, r]" <> " = " <> ToString[Fit[currentRatio[32],1,x,x^2,x^3,x]/.x->"Subscript[I, r]"]

produces the garbled output

Subscript[I, m]/Subscript[I, r] = -6 2 -10 3
0.591585 + 0.00126235 I - 1.75804 10 I + 8.08979 10 I

"Subscript[I, m]/Subscript[I, r]" <> " = " <> 
 ToString[Fit[Table[x, x + x^3, x, 0, 1, .1], 1, x, x^2, x^3, x] /. 
 x -> "Subscript[I, r]", StandardForm]

enter image description here

With InputForm inplace of StandardForm we get

"Subscript[I, m]/Subscript[I, r] = 0. +

Just use Row:

Row[
 Subscript[I, m]/Subscript[I, r] , 
 " = ", 
 Fit[Table[x, x + x^3, x, 0, 1, .1], 1, x, x^2, x^3, x] /. 
 x -> Subscript[I, r]
]
