Zoledronic acid did not impact cortical porosity at either site but increased cortical thickness ( 3 . 0 +/- 3 . 5 % , p < 0 . 01 ) , total ( 2 . 7 +/- 2 . 5 % , p < 0 . 001 ) and cortical density ( 1 . 5 +/- 2 . 0 % , p < 0 . 01 ) in tibia as well as trabecular volume fraction in radius ( 2 . 5 +/- 5 . 1 % , p < 0 . 05 ) and tibia ( 2 . 2 +/- 2 . 2 % , p < 0 . 01 ) .
