Question

Choose the study design that best fits the following description: A random sample of middle-aged sedentary women was selected from four neighborhoods, and each participant was examined for evidence of osteoporosis. Those found to have the disease were excluded. All others were randomly assigned to either an exercise group or a control group, which had no exercise program. Both groups were observed semiannually for incidence of osteoporosis.

a) Case Control Study

b) Randomized Clinical Trial

c) Cross Sectional Study

d) Prospective Cohort Study

e) Retrospective Cohort Study

f) Ecologic Study

Answer 1

ANSWER:-"b"

"RANDOMIZED CLINICAL TRIAL "

The study design that best fits the following description was randomized clinical trial.because the women are randomly allocated to two groups one is excercise group and other one group is control group with out excercise program and these groups are observed semiannually for better intervention.

CONCLUSION:-

Women are randomly allocated to each gropg for better intervention.it helps to determine whether exercise will decrease the incidence rate of osteoporosis or not.

so randomized clinical trail in this randomization is way to reduce bias when testing new treatment or for new intervention.

so randomized clinical trail study design is efficient for research studies.
