This special issue comprises four articles – two use common meta-analysis techniques to perform a quantitative review of topics in the audit research literature (Alareeni, 2018; Durand, 2018), one is a commentary that encourages audit researchers to use a newer technique called meta-regression (Hay and Knechel, 2017) and highlights the potential role that a well-designed meta-analysis can play in informing evidence-based standard setting (Hay, 2018), and the last is not a meta-analysis per se, but does introduce to audit researchers a quantitative technique called citation count regression that, like meta-analysis, can be used to enhance a narrative literature review (Staszkiewicz, 2018). All of the articles focus, for the most part, on the archival audit literature.
