The Hoorn Studies
There Are 4 types of clinical Research : -
Etiologic 9 occurrence of Disease
-
Diagnostic > predicts presence of Disease
-
Prognostic >predicts course of Disease
- Intervention 9 Defines medical Action .
For etiology research the Aim is to Assess the cause
of the Disease The RQ is made to Determine the
.
Association between Determinant & outcome .
The characteristics Are :
-
Explanatory Research
-
Demonstrate causality
- Determinant & Exposure occur before outcome
-
study Design = prospective effect
-
A
confounding variable is A variable that correlates
with both Dependent & independent variable It affects .
the variables being studied so that the results Do not
reflect the Relationship between them .
A
mediating variable is A variable that Links the
independent AND Dependent van .
, ans whose existence
explains the Relationship between the 2 variables .
In A Diagnostic Research ,the Aim is to Assess the presence or Absence of A
particular Disease The RQ is made to quantify
.
whether ants to what extent ☐ test contributes to
the Detection of those with the Disease .
The characteristics Are :
←
-
Study Design > cross-sectional
-
Descriptive research
- Determinants, gold standard & outcome are Assessed at
same time .
