A funnel plot is a useful graph designed to check the existence of publication bias in systematic reviews and meta-analyses. It assumes that the largest studies will be near the average, and small studies will be spread on both sides of the average. Variation from this assumption can indicate publication bias.
Famous quotes containing the word plot:
“The plot was most interesting. It belonged to no particular age, people, or country, and was perhaps the more delightful on that account, as nobody’s previous information could afford the remotest glimmering of what would ever come of it.”
—Charles Dickens (1812–1870)
