A Simple Bayesian Method for Evaluating Whether Data From Patients With Rheumatic Diseases Who Have Been Under Chronic Hydroxychloroquine Medication Since Before the COVID-19 Outbreak Can Speak to Hydroxychloroquine's Prophylactic Effect Against Infection With SARS-CoV-2 2020-08-13 .txt text/plain 4364 190 54 title: A Simple Bayesian Method for Evaluating Whether Data From Patients With Rheumatic Diseases Who Have Been Under Chronic Hydroxychloroquine Medication Since Before the COVID-19 Outbreak Can Speak to Hydroxychloroquine's Prophylactic Effect Against Infection With SARS-CoV-2 We propose to use data from patients with rheumatic diseases (RA, SLR) who have been chronically taking HCQ medication since before the COVID-19 outbreak (hereafter: HCQpa), in order to evaluate the potential of HCQ for preventing infection with SARS-CoV-2. If HCQ has no prophylactic effect against infection with SARS-CoV-2, COVID-19 prevalence in HCQpa will not be statistically different from that in the general population (all comers who do not take HCQ medication; hereafter: pop gen ). HCQ having a prophylactic effect against SARS-CoV-2 infection would manifest itself by a COVID-19 prevalence in HCQpa that is lower than the COVID-19 prevalence in the general population. ./cache/cord-301025-cf2jcw6x.txt ./txt/cord-301025-cf2jcw6x.txt
