Various
data fields in the EDF require entry of valid values. Valid values are
built-in codes that the format requires for certain fields, such as
contractor names, matrices, and laboratories. The reason for using
specific values for these fields is to standardize data entry, to
ensure data consistency and prevent errors. Freely entered data might
contain extra spaces, commas, or dashes that would make meaningful data
manipulation and thorough or accurate data searches impossible.
