  1. Below are the data you collect, based on a prospective cohort study in which non-obese children were followed over 10 years. Children in the top 25th percentile of self-reported SSB consumption during the first year of the study were categorized as SSB consumers. All other children were categorized as non-SSB consumers. Blood was drawn from the children at enrollment, and all were tested for the presence of the genetic variant. Calculate the appropriate measures of the crude association between SSB consumption and obesity status, with 95% confidence intervals.

A ["prospective", OR "retrospective"] cohort study is carried out to investigate the association between occupational arsenic inhalation and neurological exposure and neurological effects among workers in a copper smelter. For the sake of simplicity, let’s assume there are two possible exposure categories: high and low (for example, those working in the smelting process and those working in administration). The exposure was carefully assessed by review of company records which reflected very good exposure monitoring (both air sampling and urine testing)....
