Help me translate some tricky grammar

Question

Hi all,

I am trying to translate this phrase:

""In addition, any new treatment must be shown to be more effective than those currently available for Parkinson's, which this treatment has not yet been shown to be."

I find this grammar to be quite a challenge. Here is what I came up with:

“Además, se debe mostrar que cualquier nuevo tratamiento sea más efectivo que aquellos que ya son disponibles para Parkinson, lo cual no se ha mostrado que este tratamiento lo sea.”

I have no idea if I am anywhere close to on the right track here. Can anyone help me figure out this enigma wrapped in a riddle surrounded by a question mark?

Answer 1

Hi, hiladora!!

My suggestion:

Además, cualquier nuevo tratamiento debe demostrar ser más efectivo que los actualmente disponibles para la enfermedad de Parkinson, cosa que éste todavía no ha demostrado.

Thanks, this seems like a clearer way of phrasing it. - hiladora, Mar 21, 2011

Answer 2

I am wondering about the 'aquellos'. Perhaps 'los' instead?

Grammatically los and aquellos should function the same in this case, its just more of a question of "distance" (if that makes any sense). Here's more info about it:http://www.studyspanish.com/lessons/demonstratives.htm - hiladora, Mar 21, 2011

I was thinking "los", too. aquéllos is normally used when there is an éstos or ésos to compare to. Why not shorten the ending to: lo cual no ha demostrado este tratamiento. - 0074b507, Mar 21, 2011
