Case SeriesClinical

A report of outcomes in a group of patients with no comparison group.

A case series describes outcomes in a cohort of patients who underwent the same intervention without a control or comparator arm. It sits low on the evidence hierarchy because it cannot separate treatment effect from natural history or selection, which matters when an entire literature is built largely from small series of this type.
