Several statistical methods that are available in the literature to analyze postmarket safety databases, such as the U.S. Federal Drug Administration’s (FDA) adverse event reporting system (AERS), for identifying drug-event combinations with disproportionately high frequencies, are subject to high false discovery rates. Here, we propose a likelihood ratio test (LRT) based method and show, via an extensive simulation study, that the proposed method while retaining good power and sensitivity for identifying signals, controls both the Type I error and false discovery rates. The application of the LRT method to the AERS database is illustrated using two datasets; a small dataset consisting of suicidal behavior and mood change-related AE cases for the drug Montelukast, and a large dataset consisting of all possible AE cases reported to FDA during 2004–2008 for the drug Heparin.
