-An Adjusted Rate Ratio (ARR) is a variant of the PRR used by analysts working with the Vaccine Safety Datalink (VSD).  The VSD is a collaborative project between the CDC and nine integrated health care organizations, most of which are part of the Kaiser Parmanente network(("Vaccine Safety Datalink (VSD)." https://www.cdc.gov/vaccinesafety/ensuringsafety/monitoring/vsd/index.html)). The stated goal of the VSD is to use Rapid Cycle Analysis (RCA) to "detect adverse events following vaccination in near real time so the public can be informed quickly of possible risks.(("Rapid Cycle Analysis." https://www.cdc.gov/vaccinesafety/ensuringsafety/monitoring/vsd/index.html#RCA))" The VSD RCA does not completely define what it calls Adjusted Rate Ratios, but the resulting statistics appear to be PRRs with some form of adjustments for data collection sites, demographics, etc. These adjustments, however they are calculated, have nothing to do with the problems inherent in the use of PRR in safety signal detection, however.
