check_ae_aeacnoth: Check for null AEACNOT1/2 when AEACNOTH = 'MULTIPLE'

In sdtmchecks: Data Quality Checks for Study Data Tabulation Model (SDTM) Datasets

Check for null AEACNOT1/2 when AEACNOTH = 'MULTIPLE'

Description

Flag if patient has a record with null values of AEACNOT1 and AEACNOT2 but AEACNOTH = 'MULTIPLE', so a likely mapping issue

Usage

check_ae_aeacnoth(AE, preproc = identity, ...)

Arguments

AE	Adverse Events SDTM dataset with variables USUBJID, AETERM, AESTDTC, AEACNOTH, AEACNOT1/2, AESPID (optional)
preproc	An optional company specific preprocessing script
...	Other arguments passed to methods

Value

boolean value if check failed or passed with 'msg' attribute if the test failed
