This study aimed to evaluate the effect of H2 receptor antagonists and proton pump inhibitors on the clinical outcomes and positivity rates of COVID-19 using the Korean National Health Insurance (NHI) data. This is a retrospective cohort study using the NHI COVID-19 dataset, which includes health insurance data of individuals who underwent COVID-19 PCR test in South Korea. This study aims to evaluate the effect of the use of PPI and H2RA on the positivity rates and clinical outcomes of COVID-19.
