<qa>  What was the PK Evaluable Population used for?The concentration of CD24Fc was summarized descriptively at each nominal time point by treatment e.g., n, mean, standard deviation SD, coefficient of variation CV, standard error, median, minimum, and maximum. Mean concentration SD was plotted on a linear scale against nominal time points by treatment. Geometric mean concentration was plotted on a semi-logarithmic scale against nominal time points. The PK Evaluable Population was used for the summary and individual concentrations.
