The SERC PSG Data Dictionary is a new approach to the documentation of PSG data
that provides definitions and descriptions of over 1,500 PSG and epidemiological
and demographic covariate variables,
powered by an interactive web interface. This platform gives the user flexibility
to browse the database by category or to search for text, thus quickly
locating information about particular variables or finding variables that contain
certain types of information. The data dictionary is also dynamically linked to study
databases in the PSG PhysioRepository in order to return distribution and frequency
statistics on each of the variables as they are being viewed.
