From the first question, which study design is best to determine the risk factor to hutchinson -gilford -prudgeria or rare genetic condition that causes a child's body to age fast? the correct answer for question number one is case control.

02:11
So analytic will provide those cases to have a valid reason and to have those data that can be provided based on this diseases that being accumulated to the body.

Question number four.
