Question

Suppose the data in the table below was found from a case-control study. What measure of association would you calculate, what is the value of the measure and it's 95% CI? Is it significant?  Why or why not?

	case	control
exposed	37	77
non-exposed	120	390

	a	RR, 1.38, (1.01, 1.88), significant since 0 is not contained in the confidence interval
	b	OR, 1.56, (1.00, 2.43), significant since 0 is not contained in the confidence interval
	c	RR, 1.38, (1.01, 1.88), significant since 1 is not contained in the confidence interval
	d	OR, 1.56, (1.00, 2.43), significant since 1 is not contained in the confidence interval
	e	none of the above
