Question 1 A researcher conducted a study to examine the association between having a central venous catheter and the risk of developing bloodstream infection (measured as infected vs. not infected). The results for this association show an odds ratio (OR) of 1.52 with a 95%CI of (1.29 – 2.15). Thus you conclude that……………………………….

The study is conducted to investigate the association between chewing tobacco
CASE ONE The study is conducted to investigate the association between chewing tobacco and oral leukoplakia (a precancerous lesion) among currently active professional baseball players in the southeastern United States. A roster of all active players is obtained (n=500). All potential study subjects agree to participate. Each subject has an interview regarding current use of chewing tobacco and has his mouth examined by a dentist. Of the 500 subjects, 125 subjects chew tobacco and 375 do not chew tobacco. Of the...
