This process requires AE and either DM or ADSL . Required variables include USUBJID and AEDECOD . AELLT is desirable, but optional.In addition, several text files defining MedDRA terms are required. These include: mq_content.asc (lists preferred and lower level terms associated with the queries), smq_list.asc ( list of SMQs), pt.asc (lists preferred terms and codes), and llt.asc (lists lower-level terms and codes).The output generated by this process is summarized in a tabbed report.
