A Model of Implant-Associated Infection in the Tibial Metaphysis of Rats

Table 3

Statistical significance (expressed in 𝑃 values) of bacterial counts derived from test Groups I to V as determined by the concerning Mann-Whitney test between groups I to V from the periprosthetic bone (a) and the implant sonification fluid (b).
