The weaknesses of cross-sectional studies include
the inability to assess incidence, to study rare diseases, and to make a causal inference
. Unlike studies starting from a series of patients, cross-sectional studies often need to select a sample of subjects from a large and heterogeneous study population.

What is an advantage of a cross-sectional study?
Cross-sectional studies permit
researchers an opportunity to study multiple outcomes and exposures simultaneously
. That allows multiple variables to be accessed simultaneously, which increases the accuracy of an assessment on the burdens of a data point within the specific population group.
What is a con of a cross-sectional study?
Cross-sectional studies may involve
special data collection, including questions about the past
, but they often rely on data originally collected for other purposes. They are moderately expensive, and are not suitable for the study of rare diseases. Difficulty in recalling past events may also contribute bias.

Do cross-sectional studies have a control group?
