Question

A doctor conducted further clinical trials on the new drug’s relationship to patient wound healing times; building on her previous study, she was interested in the potential mediating effects of patient age. She conducted a mediation analysis and had the following output: b = 0.31, 95% CI [0.01, 0.30], p = 0.054. How would you interpret her results? a. There is no indirect effect between the new drug and patient wound healing times mediated by patient age b. There is a direct effect between the new drug and patient wound healing times not mediated by patient age c. There is an indirect effect between the new drug and patient wound healing times mediated by patient age d. There is an indirect effect between the new drug and patient wound healing times not mediated by patient age

Answer 1

Here we want to test that the he new drug’s relationship to patient wound healing times mediating effects of patient age.

Ho:-There is no indirect effect between the new drug and patient wound healing times mediated by patient age

v/s

Ha:-There is an indirect effect between the new drug and patient wound healing times mediated by patient age

Confidence interval = [ 0.01,0.30]

we reject Ho if confidence interval does not contain 0.

Here confidence interval does not contain 0.

so we reject Ho.

There is an indirect effect between the new drug and patient wound healing times mediated by patient age .

Answer:- c. There is an indirect effect between the new drug and patient wound healing times mediated by patient age
