Cumulative P24 Antigen v. TFV Concentration across all matrices by product. Regression lines are not shown since no linear regression fitting demonstrated statistically significant slopes (none different from slope=0). Baseline values arbitrarily imputed as 0.01 units in each panel. Concentration values below the lower limit of assay quantitation (LLOQ) calculated for each individual sample are imputed as LLOQ/2 for the median calculated LLOQ.
