Create a code list

Code lists allow study designers to easily add standard answer options to a drop-down, checkbox, or radio button type question.

Code lists are sets of predefined data that also include standard codes for data analysis. To adhere to SDTM terminology sets and follow the industry's standards, code lists must contain proper codes. In turn, this allows data managers and statisticians to more easily analyze extracted data. For more information on data extracts, see the Subject Data Extract.

Note:

Custom code lists that you create on the Code List tab (in a study's settings) are displayed in the Code List dialog box when you choose to apply a code list to a question. For more information, see Create a custom code list.
