Table 2 Impact of COVID-19 on the risk of newly diagnosed autoimmune disease (COVID-19 versus non-COVID-19). Hazard ratio (HR) and 95% confidence interval (95% CI) estimated by Cox regression. HR > 1 (or <1) means that patients with COVID-19 had a higher (lower) risk of newly diagnosed autoimmune disease than the control cohort without COVID-19. Error bars indicate the 95% CI of the respective HR (with permission of Peng et al. (2023))
