The VL data from each donor was fit using the target cell-limited model and models that incorporated the effects of anti-gp41 IgG or IgM and IgG plus IgM. CE, clearance enhanced; ID, infectivity diminished; CDE, cell death enhanced. The models with antibody effects include one additional parameter, which when set to zero reduces the model to the target cell-limited model. An F-test was used to determine if any of the models including antibody fit the VL data significantly better than the target cell-model. The table gives the P values computed from the F-test.
