Note: Units must be added to the time and concentration columns before the dataset can be used in a noncompartmental analysis. Import the file …\Examples\WinNonlin\Supporting files\Bguide1 single dose and steady state.dat. Set up the project and data for the three profiles The completed project ( NCA.phxproj) is available for reference in …\Examples\WinNonlin. Suppose a researcher has obtained time and concentration data following oral administration of a test compound to three subjects, and wants to perform noncompartmental analysis and summarize the results. Knowledge of how to do basic tasks using the Phoenix interface, such as creating a project and importing data, is assumed. This section presents several examples of the NCA operational object usage within Phoenix.
