drdoomAs Aristotle once quipped, “A ‘single-point in time’ doth not a cross-sectional study make.” The design of a cross-sectional study would not define “ahead of time” two cohorts (two groups); said another way, a cross-sectional design would not “split people into two groups.” In the design of a cross-sectional study there is only “one group”, and then you ask all members of that group some question (“Do you have asthma?”). At the end of a cross-sectional study, the authors will be able to make a statement like this: “We called 10,000 phone numbers with area code 415 at random and asked ‘Do you take Drug X?’ 500 responded ‘I don’t know’, 633 responded ‘Yes’, and 8,867 responded ’No’.”+12019-08-01T20:18:35Z
impostersyndromel1000this is one of those Qs where you just dont over think it and focus on your first point, that they are comparing a group with the disease vs (potentially) one without it.
