does the following sentence make sense?
In general, triple combinations are better than double: melphalan, prednisone and thalidomide (MPT); bortezomib, melphalan, and prednisone (VMP); or melphalan, prednisone and lenalidomide (MPR), are all better than melphalan and prednisone (MT) alone.
Is that an ok thing to say that a; b; or c is better than d? Or should it be, a; b; and c are all better than d?
I am not sure how to explain, but is the sentence ok? Thank you so much for your help!
