Question

A group of 250 women over the age of 40 are recruited for a study to determine the effects that calcium has on bone health. Half of the participants are given a calcium supplement and the other half are given a placebo. If 13 women on calcium develop osteomalacia and 27 women not on the placebo develop osteomalacia, the relative risk for developing osteomalacia for women over 40 on a calcium supplement is 0.48 when compared to those women not taking a calcium supplement. This indicates that taking calcium has no effect on the population of interest's health because the relative risk is less than 1.0.
A. True
B. False

Answer 1

Answer:

A. True

Explanation:

The result indicates that taking calcium has no effect on the development of osteomalacia in the women. This is because, of the over 120 women placed on the calcium supplements, it happens to be minimal number of people ( less than 20 people) that develop the osteomalacia disease of the bone.
