weakest design
retrospective
strongest design
expiermental
* randomized control trial

preventative and therapeutic trials
how do case control studies work
work backwards from the effect to the suspected cause
compare subjects with a disease and matched subjects without the disease
advantage of cohort studies
minimize selection bias
cohort studies how do they work
monitor subjects over time to find associations between risk factors and health outcomes
gold standard for research is
randomized control
what is quasi experimental
it is analytic experimental
what can quasi experimental be used to find
causality
what is systematic reviews
collection of studies
