Dr. Harvey Risch's presentation at the C19 minisymposium session, November 7 2021
Hydroxychloroquine and Other Outpatient Treatments for Covid-19, with Critique of Epidemiologic Methods
Abstract: To most academics and clinicians, the field of epidemiology seems like a no-brainer--you just get some cases and controls, run some regression models if you are a quant, and see what's different. Is there really any science there? Epidemiology is indeed a science but what is scientific about it per se is subtle. The crucial scientific aspect about epidemiology is representativeness: that the patients are generalizable to the disease as a whole, the controls are generalizable to the population of relevance, the exposure measures accurately reflect what the subjects really experienced, and the exposure association is not reflective of some other reason why an association is present. Epidemiologists agonize over these issues in terms of bias and confounding, as well as misrepresentation of studies, cherry picking and other more general corruptions of the scientific method. In this talk, I will discuss how non-scientific factors created aberration of knowledge greater than the scientific evidence itself, and show what the evidence for early treatment really does show.
