TFV and TFVdp dose, p24 suppression response non-linear models.

p = probability of non-linear model fit.ns = non-significant at alpha 0.05.n = number of CC:p24 paired measurements.r2 = (1-) the sum of the squared distances from each fitted curved divided by the squared distances from a horizontal line.*AIC = Akaike information criterion value. The 3-parameter non-linear model provided lower AIC values indicating a better fit than an alternative 4-parameter model.§3-parameter model: §§4-parameter model: TFV and TFVdp dose, p24 suppression response non-linear models.
