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:
“Ends in themselves, my letters plot no change;
They carry nothing dutiable; they won’t
Aspire, astound, establish or estrange.”
—Philip Larkin (1922–1986)
