Transcribed Image Text:Below are the results of a prospective cohort study that investigated the relationship between
occupation (grocery store clerk versus convenience store clerk) and post-activity polypnea (difficulty
breathing following exertion) in 1000 persons suffering from Post-acute COVID Syndrome. In the
table below, E+ identifies grocery store clerks (the exposed group) and E- identifies convenience
store clerks (the unexposed group). D+ and D- represent the presence or absence of post-activity
polypnea, respectively. Obesity is a potential confounder.
