Abstract: Objective To survey and compare likelihood ratio test (LRT) approaches to post-marketing safety surveillance. Methods The fundamentals of likelihood ratio tests as well as the advantages and disadvantages of each method were summarized. Meanwhile, priorities of research in the future were predicted. Results Existing evidence suggested that LRT methods could better control type I errors than the reporting odds ratio and information component methods. Besides, LRT approaches employed a class of precise statistical tools which enabled objective evaluation under various scenarios. Conclusion LRT methods are feasible for post-marketing safety surveillance, especially when rigorous control of the false discovery rate is required or when a trade-off between the false discovery rate/type I error incidence and sensitivity/power is needed. However, there are still some problems that remain unsettled.

Key words: likelihood ratio test, post-marketing safety surveillance, type I error, reporting odds ratio, information component methods
