Doxy and ceft.

I'm curiously, but i've seen three articles where compare doxy vs rocephin and finally there is a little better % of succes with doxy at late stage neuroborreliosis, and less relaprelapsedse. Does it mean doxy is better than rocephin?

There is something that my doctor said me that made me think. People know the effects of high doses IV antibiotics and effects of low dose oral antibiotics.
