Disadvantage of cohort study?

In: Laboratory Testing [Edit categories]

Answer:

• Cohort studies describe incidence or natural history.
• They analyse predictors (risk factors) thereby enabling calculation
of relative risk.
• Cohort studies measure events in temporal sequence
thereby distinguishing causes from effects.
• Retrospective cohorts where available are cheaper and
quicker.
• Confounding variables are the major problem in analysing
cohort studies.
• Subject selection and loss to follow up is a major potential
cause of bias.
