Which of the following statements correctly summarises this result? Question 19 options: a) The risk of developing depression is the same for those who eat unhealthy foods at least three times per week and those who eat unhealthy foods once per week because the relative risk is not statistically significant b) Those who eat unhealthy foods at least three times per week have a statistically significant 60% greater risk of depression than those who eat unhealthy foods once per week c) Those who eat unhealthy foods at least three times per week have a statistically significant 60% reduced risk of depression than those who eat unhealthy foods once per week d) Those who eat unhealthy foods at least three times per week have a statistically significant 40% reduced risk of depression than those who eat unhealthy foods once per week e) Those who eat unhealthy foods at least three times per week have a statistically significant 40% greater risk of depression than those who eat unhealthy foods once per week

Answer 1

The correct answer is option option b - Those who eat unhealthy foods at least three times per week have a statistically significant 60% greater risk of depression than those who eat unhealthy foods once per week
