A heart study objective was to study heart disease among healthy volunteers. After a 10-year follow-up period involving men aged 40 to 59, there were 16 cases of coronary heart disease (CHD) among the 454 men who initially had cholesterol levels below 210 mg/100 ml (referred to as the low serum cholesterol group). In contrast, among the 424 men whose initial cholesterol levels were at least 245 mg/100 ml (referred to as the high serum cholesterol group), there were 51 cases of CHD. With this information, Draw a 2x2 contingency table then calculate the relative risk (RR) associated with high serum cholesterol and provide an interpretation of the result.

With this information, Draw a 2x2
Let's construct a 2x2 contingency table based on the provided information:
CHD Cases | No CHD Cases | Total | |
Low Cholesterol | 16 | 438 | 454 |
High Cholesterol | 51 | 373 | 424 |
Total | 67 | 811 | 878 |
