Impact Factor

Abstract

How likely is it that a scientific article will still be being cited half a century after it first appeared? A working group around John P. Ioannidis of Stanford University has investigated the fate of more than 5000 contributions in 27 medical journals from the year 1959 (1), and found that no fewer than one in 23 of these texts received a citation in 2009. Classic status, however—at least five citations—was attained by only one in 400 publications; examples given in the study are the descriptions of Prinzmetal’s angina or Down syndrome.

No public copy is stored for this record, so only the metadata is cited.

Stored only when both papers are in the corpus — 19 citations exist upstream.

Papers that cite the same references — the relational fallback while embeddings are still backfilling.
