Study Design for Clinical Research Flashcards
this kind of study described data in basic quantitative terms (e.g. # of occurrences of an outcome)
Descriptive Study
These are 3 types of analytical studies
- cross-sectional studies
- Case-control studies
- Cohort studies
This type of study is the simplest of observational studies
descriptive study
This type of study can include case reports & case studies as data sources
Descriptive study
This type of study is useful for generating rates of an outcome, identifying populations at risk, or formulating hypotheses about cause of a given outcome
descriptive study
this type of study takes a snapshot of a sample population hat includes the outcome of interest and potential risk factors
cross-sectional study
this type of study measure both preexisting and new outcomes
cross-sectional study
this type of study can only determine prevalence
cross-sectional study
cross-sectional studies cannot assess
cause & effect
this type of study determines risk-factors & outcome data simultaneousy
cross-sectional study
this type of study compared individuals with outcome of interest to control group of individuals without outcome
case-control studies
This type of study although similar to, is faster and cheaper than cohort studies
case-control studies
this type of study is suited for studying relatively rare outcomes or those that develop a longtime following exposure
case-control studies
This study type assess individuals with and without exposure to a potential risk factor who did not have the outcome of interest at study enrollment
cohort study
in this study incidence of the outcome is determined during follow-up observation & compared for the exposed and the unexposed individuals
cohort study
this study is better suited for assessment of outcomes with short latency period after exposure
cohort study
cohort studies are conducted
prospectively
this type of study may provide more compelling evidence for casual association than do case case-control
cohort study
