Because the PhenX Toolkit includes detailed protocols for obtaining data on the measures, Toolkit users can review and assess whether or not a specific protocol is suitable for their study. The expectation is that researchers who visit the Toolkit site will be able to identify some PhenX measures that are suitable for their study population and their available resources. Figure 2 presents a screen shot of the home page of the PhenX Toolkit; a general summary of the PhenX Toolkit is shown in Table 2 (17).
