Question

Three medications aimed at preventing the loss of bone density may also suppress the body's ability to replace older bone tissue with new bone tissue. Among 52,595 treated women, an unusual fracture occurred in 117. What is the absolute risk, as a percent?

a) 0.22%

b) 0.45%

c) 1.23%

d) 2.11%"

Answer 1

The absolute risk of an unusual fracture among treated women is calculated by dividing the number of women who experienced the fracture (117) by the total number of women at risk (52,595) and multiplying by 100. The result is approximately 0.22%, which corresponds to option a).

Step-by-step explanation:

The student is asking about the calculation of absolute risk as a percentage. Absolute risk is a measure of the likelihood of an event occurring within a specific population over a period of time. To calculate the absolute risk, divide the number of people who have experienced the event by the total number of people at risk, and then multiply by 100 to convert to a percentage.

In this case, the event is the occurrence of an unusual fracture among treated women. The number of women who experienced the event is 117, and the total number of women at risk (the total number being treated) is 52,595. Therefore, the absolute risk is (117 / 52,595) × 100, which is approximately 0.2223%. The closest answer in percentage form rounded to two decimal places is 0.22%, which is option a).
