2.6.5 Handling of OpenClinica Null values

When creating an Event Definition, the user can choose to allow certain codes to represent null values in the entered data. Examples are ‘NI’, ‘NA’ etc.

If a non-string item has one of the allowed OpenClinica null values as item data, SPSS will treat it as a system missing values, and an empty data is cell is displayed in the Data View of the SPSS tool. In case of an item of data type string (ST), the null value string is displayed as is.
