A large case-control study was conducted to assess the relationship between tampon use and toxic shock syndrome (TSS). The odds ratio for tampon use among patients with TSS compared to healthy subjects (controls) was reported as 5.0 (95% confidence interval [4.7-5.2), p <0.01). The authors concluded that the risk of TSS was approximately 5 times higher in tampon users; this was based on the assumption that odds ratio is a good approximation of relative risk in this study. Which of the following best supports this assumption?
A. The confidence interval for the odds ratio is narrow
B. The exposure is associated with the disease
C. The incidence of toxic shock syndrome is low
D. The odds ratio is highly statistically significant
E. The sample size is large
