Der var dog ingen forskel i forekomsten af disse bivirkninger sammen med patienter, der fik knogleimplantater i stedet for Osigraft, undtagen i tilfælde med osteomyelitis (infektion i knoglen), hvor forekomsten af osteomyelitis var statistisk højere end i autograft- gruppen.
However, there were no differences in the incidence of these adverse events compared with patients who received bone autograft (transplanted bone) instead of Osigraft, except in the case of osteomyelitis (infection of the bone) for which the incidence of osteomyelitis was statistically higher in the autograft group.
