Cohort studies can be distinguished as either prospective or retrospective A prospective cohort study begins with the selection of two groups of non-diseased animals, one exposed to a factor postulated to cause a disease and the other unexposed. Pre-term labour, postpartum infections in the mother or infant, and admission to the neonatal intensive care unit were equally common in both groups.

Synonyms for exposure are: Case-control studies are an efficient method for studying rare diseases. A key feature of ecological studies is that inference can only be made at the group level, not at the individual level.

Controls were sampled to match the cases on age, sex, race and month of admission.

Women were randomly assigned to receive either: Individuals included in the sample are examined for the presence of disease and their status with regard to the presence or absence of specified risk factors.

A special surveillance unit was set up to study Creutzfeld-Jacob disease CJDa rare and fatal progressive dementia that shares clinical and pathological features of BSE.

Each case and control was then interviewed about any past subscription to a cellular telephone service. Ecological studies are relatively quick and inexpensive to perform It can provide clues to possible associations between exposures and epidwmiologi of interest.
