Landscape Analysis of Background Rates Methods and Dashboard to Capture Background Rates of Interest for COVID-19 AESI Methods

This document describes the methods for the systematic literature search, screening and the extraction of information from published documents, that capture information on incidence rates for any of the AESI in tier 1-4. It also describes how this information can be displayed visually on the Brighton Collaboration website. The approach chosen for the dashboard was to retain as much information as possible, in the underlying extracted data, which are quite heterogeneous in terms of methodology in particular geographic area, age classification, study years as well as age range, case identification and ascertainment processes Maintaining that information in a structured manner will allow the user to select as needed.
