With an n often of 1, its significance is never statistical and its message rarely generalizable. Compared with its big sisters, the full-length clinical and research articles, the lowly case report has less text, fewer references, and often not even a page of its own.

For example, the observation that some patients with diabetes who had large chorioretinal scars never developed proliferative retinopathy led to considering panretinal photocoagulation as a therapy.
